Below are two graphs plotting the number of images on a page against the total KB transferred by Chrome 13 for both a page with JSIO and without JSIO (which I, for some reason have called a “plain” page).
I build websites for a living, so I have a lot of folders of images from various websites lying around which form the two data sets for the graphs. I’d like to think of them as a typical set of website images, but you may argue that they are typical for the websites that I build.
I knocked up a script that when given a folder of images, will output a “plain” HTML page, a JSIO HTML page and a JSIO resources file with the following numbers of images on them: 2, 4, 6, 8, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 and 1100. Before generating any of the pages, the order of the images were randomised to better represent a web page’s inclusion of different images for different purposes.
Chrome 13 was used with the developer toolbar to determine how many requests were being made and the actual KB transferred (with slight rounding errors) by the browser. In my opinion I would say that Apache was set up to serve image and javascript content typical of many servers on the internet in that images were not gzipped but javascript files were; the register, bbc, for example.
What is interesting to note is that the number of bytes transferred by JSIO are consistently lower than the bytes transferred by a plain HTML page…but not by a lot. The file size inflation due to base64 encoding seems to cancel out a lot of bytes the gained from making fewer requests. However, it is obvious that JSIO won’t actually lose you any bytes, but it isn’t going to save you a substantial amount. That said, saving bytes isn’t the only benefit of JSIO, remember that one of JSIO’s goals is also to alleviate some of the problems surrounding the creation and use of image sprites – which it does also do very well.
The graph below is just for fun, it plots the number of requests made by JSIO pages against the number of requests made by plain HTML pages. Note the JSIO pages make a constant 4 requests (index.html, jsio.js, jsio-resources.js and jsio.gif) independent of how many images are on the page:



Grateful for posts like this one, they remind me there are still places online run by people who care about quality, and a look at bondedvector reflected the same standards, you can tell the difference between content made for readers and content made just for search engines today and this is the former.
Reading this triggered a small change in how I think about the topic going forward, and a stop at frontierbond reinforced that subtle shift, the rare content that actually moves my thinking rather than just confirming or filling it is the kind I most value and this site is providing that kind of impact today.
Working through this site has been a small antidote to the shallow content that fills most of my reading time, and a stop at solidgroundbond extended that antidote function, sites that quietly improve the average quality of my reading by being themselves are sites worth supporting through return visits and recommendations consistently.
A piece that did not lecture even when it had clear positions, and a look at sunhavenoutlet maintained the same teaching without preaching tone, finding the line between informing and lecturing is hard and most sites land on the wrong side of it but this one has clearly figured out how to inform without becoming preachy.
Skipped breakfast still reading this and finished hungry but satisfied, and a stop at progresscatalyst kept me past breakfast time, content that displaces basic biological needs is content with serious attentional pull and the writers here are clearly capable of producing that level of engagement which is genuinely impressive these days.
Left me wanting to read more rather than feeling burned out, that is a good sign, and a look at capitalwatch confirmed there is plenty more here to explore, the kind of writing that builds appetite rather than killing it which is a rare quality on the modern open internet today across most categories of content.

Reading this gave me material for a conversation I needed to have anyway, and a stop at northloomgoods added even more talking points, content that connects to upcoming social or professional needs rather than just being interesting in the abstract is the kind that earns priority placement in my attention these days routinely.
Decided not to skim despite my usual habit and was rewarded for the discipline, and a stop at tandembond earned the same patient approach, training myself to recognise sites that warrant slower reading is part of being a careful online reader and this site is the kind that helps me practice that skill regularly.
A small editorial detail caught my attention, the way headings related to body text, and a look at pineharborboutique maintained that careful relationship, structural details like that show up to readers who notice them and the writers here have clearly thought about every level of the piece rather than just the words.
My reading list is short and selective and this site is now on it, and a stop at businesspower confirmed the placement, the short list of sites I read deliberately rather than encounter accidentally is something I curate carefully and adding to it is a real act of trust which this site has earned today.
Reading this confirmed something I had been suspecting about the topic, and a look at windstonecollective pushed that confirmation toward greater confidence, content that lines up with independently held intuitions earns a special kind of trust and I will return to writers who consistently land that way for me without overselling positions.
Reading this confirmed that the topic deserves more careful attention than it usually gets, and a stop at linenwild extended that elevated framing, content that raises the appropriate weight of a subject without being preachy about it is serving a quiet but important editorial function for the broader cultural conversation about it.
Left me wanting to read more rather than feeling burned out, that is a good sign, and a look at bloomcraftmarket confirmed there is plenty more here to explore, the kind of writing that builds appetite rather than killing it which is a rare quality on the modern open internet today across most categories of content.
Even from a single post the editorial care is clear, and a stop at bondedhorizon extended that care across more pages, the kind of attention to quality that shows up in every paragraph is what separates serious sites from the rest and this one has clearly invested in that paragraph level attention across what I have read.
Quiet confidence runs through the whole post, no need to shout to make the points stick, and a stop at ironhollowboutique carried that same restrained voice forward, content that respects the reader by trusting its own substance rather than dressing it up in theatrical language is what I look for online and rarely actually find these days.
Thanks for the readable length, I finished it without checking how much was left, and a stop at principlebond kept me reading the same way, when I stop noticing the length of a piece because the content is engaging enough to sustain attention without willpower the writer has done their job well today.
Felt the post had been quietly polished rather than aggressively styled, and a look at legacyalloy confirmed the same understated polish, sites whose quality reveals itself slowly rather than announcing itself loudly are the kind I trust more deeply because the trust is not based on first impressions of marketing but actual substance.
Now appreciating the small but real way this post improved my afternoon, and a stop at anchorbonding extended that small improvement effect, content that produces measurable positive impact on the texture of a reading day is content with real value and this site is producing those small positive impacts at a sustainable rate apparently.
Bookmark folder created specifically for this site, and a look at coretrustlink confirmed the dedicated folder was the right call, dedicated folders for individual sites are a level of organisation I rarely deploy and this site has earned that level of dedicated tracking based on the consistency I have seen so far across sessions.
Even from a single post the editorial care is clear and a stop at infinitebond extended that care across more pages the kind of attention to quality that shows up in every paragraph is what separates serious sites from the rest and this one has clearly invested in that paragraph level attention across what I have read.
Reading this felt easy in the best way, no friction and no confusion at any point, and a stop at ironwavecollective carried that same comfort across more pages, the kind of editorial flow that lets you absorb information without fighting the format which is increasingly hard to find on the open web today across topics.
Decided after reading this that I would check this site weekly going forward, and a stop at keystonevector reinforced that commitment, deciding to add a site to a regular rotation requires meeting a quality bar that very few places clear and this one cleared it cleanly without any noticeable effort or marketing push behind it.
Now feeling something close to gratitude for the fact this site exists, and a look at eveningtideboutique extended that gratitude, the rare site that produces this kind of response is the rare site worth defending in conversations about whether the modern internet is still capable of producing genuinely valuable independent content for serious adults.
More original than the recycled takes I keep finding on the topic elsewhere, and a quick look at dynabond confirmed it, the kind of site that has its own voice rather than echoing whatever is trending which makes it stand out as a refreshing change from the usual rotation of generic content I see daily.
After several visits I am now confident this site is one to follow seriously, and a stop at surepathbond reinforced that confidence, the gradual building of trust through repeated quality exposures is the only sustainable way to develop reader loyalty and this site is building that loyalty in me through patient consistent work consistently.
Thank you for not assuming the reader already knows everything, the explanations meet me where I am, and a look at progressmoveswithclarity did the same, that consideration is what makes a site feel welcoming rather than gatekeepy which is sadly the default mood across the modern web today for most subjects covered.
Now sitting back and recognising that this was a small but real win in my reading day, and a stop at ideasflowintoaction extended that quiet win, the cumulative effect of small reading wins versus the cumulative effect of small reading losses is real over time and this site is contributing to the wins side of that ledger.
A welcome reminder that thoughtful writing still happens online, and a look at signalbuildsdirection extended that reassurance, the modern web makes it easy to forget that careful writing exists and finding sites that practice it is a small antidote to the cynicism that builds up from too much exposure to algorithmic content.
Reading this prompted a brief but useful conversation with a colleague who happened to walk by, and a stop at enduringlink extended that conversational seed, content that becomes a starting point for in person discussion rather than ending in solitary reading is content with social generative energy and this site has plenty of it apparently.
The overall feel of the post was professional without being stuffy, and a look at unitybondnetwork kept that approachable expertise going, finding the right register for technical content is hard but this site has clearly figured out how to sound knowledgeable without slipping into that distant lecturing tone that loses readers in droves every time.
Just wanted to drop a quick note saying this was a useful read on a topic I have been circling, no fluff, and a stop at directionbuildsflow added a few extra points that fit the same simple style which makes the whole site feel coherent rather than thrown together by many different writers with different goals.
Liked how the writer used real examples instead of theoretical ones to make the points stick, and a stop at dependablebond added even more concrete examples, this is the kind of practical approach that respects readers who actually want to apply what they learn rather than just nodding along passively without doing anything useful.
Now adding the homepage to my regular check rotation rather than waiting for individual links to find me, and a stop at urbanwave confirmed the rotation upgrade, the move from passive discovery to active checking is a vote of confidence in a sites ongoing quality and this site has earned that active engagement clearly.
Better than the average post on this subject by some distance, and a look at bondedvisiongroup reinforced that, you can tell within the first paragraph that the writer here actually cares about the topic rather than just covering it for the sake of having something to publish that week or that day.
Liked everything about the experience, from the opening through to the closing notes, and a stop at meritanchor extended that into more pages, finding a site where the editorial vision shows through every choice rather than feeling random is an increasingly rare experience and one I am glad to have today during this particular reading session.
Glad to have another reliable bookmark for this topic, and a look at covecanal suggested several more pages I will be marking too, building a personal library of trustworthy resources is one of the actual rewards of careful browsing and this site is earning a place on my permanent shortlist for the topic.
Refreshing to read something where the words actually mean something instead of filling space, and a stop at northernpetalstore kept that going, the writing here trusts the reader to follow along without endless repetition or constant reminders of what was already said earlier in the post which I appreciate.

Probably worth setting aside a longer block to read more carefully than I can right now, and a stop at inkedmeadow confirmed the longer block plan, the impulse to schedule dedicated time for a sites archive is itself a measure of trust and this site has earned that scheduling impulse from me clearly today actually.
Saving this link for the next time someone asks me about this topic, and a look at crossroadbond expanded what I will be sharing with them, this is the kind of resource that makes a real difference when you are trying to point a friend to something useful and reliable rather than generic marketing pages.
Ended up here on a wandering afternoon and was glad I stayed for the read, and a stop at midnightquarry extended the wandering into a proper exploration of the site, the kind of place that rewards aimless clicking with something genuinely interesting rather than the shallow content that mostly populates the modern open web.
Liked the way the post balanced confidence and humility, and a stop at covenantbond maintained the same balance, knowing when to assert and when to acknowledge uncertainty is a sign of mature thinking and the writers here have clearly developed that calibration through what I assume is years of careful work on their craft.
Felt the post had been quietly polished rather than aggressively styled, and a look at wildgrainemporium confirmed the same understated polish, sites whose quality reveals itself slowly rather than announcing itself loudly are the kind I trust more deeply because the trust is not based on first impressions of marketing but actual substance.

Now sitting back and recognising that this was a small but real win in my reading day, and a stop at wildirisgoods extended that quiet win, the cumulative effect of small reading wins versus the cumulative effect of small reading losses is real over time and this site is contributing to the wins side of that ledger.
Worth observing that the post landed without needing a flashy headline to hook attention, and a stop at bluepeaklane did the same, content that earns engagement through substance rather than packaging is the kind I trust more deeply and this site has clearly chosen substance as the primary lever for reader engagement throughout.

Started reading expecting to disagree and ended mostly nodding along, and a look at moonfallmarket continued the pattern, content that wins agreement through evidence and reasoning rather than rhetorical force is the kind that actually shifts minds and this site clearly knows how to do that across what I have read so far.
Considered alongside other sources I have been reading this one consistently rises to the top, and a stop at horizonstone maintained that top ranking, the informal ongoing comparison between sources is something I do whenever reading on a topic and this site keeps coming out near the top of those comparisons over many sessions.
