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:
Different in a good way from the cookie cutter content that fills most blogs covering this area, and a stop at authenticglobalfinds kept showing me why, original thoughtful writing exists if you know where to look and this site has earned a place on my short list of those rare exceptions worth defending.
Reading this triggered a small but real correction in something I had assumed, and a stop at classystyleoutlet extended that corrective effect, content that updates my beliefs through evidence rather than rhetoric is content with intellectual integrity and this site has earned that label consistently across the pieces I have read so far today.
Now feeling slightly more committed to my own careful reading practices having read this, and a stop at softsummershoppe reinforced that commitment, content that models the kind of attention it deserves is content that calibrates the reader and this site has clearly raised my own bar for what to bring to good writing today.
Great work on keeping things readable, the post never drags or repeats itself which I really appreciate, and a stop at quillgarden added a bit more context that fit naturally with what was already said here, no need to read everything twice to get the point being made today.
Thanks for treating the topic with the seriousness it deserves without becoming pompous about it, and a stop at edgecradle continued that balanced treatment, the gap between earnest and self serious is huge and writers who can stay on the right side of it earn my respect when I find them online today.
Generally my comment to other readers about new sites is to wait and see but for this one I would jump to recommend now, and a look at urbanpasturestore reinforced that early recommendation, the speed at which a site earns my recommendation is itself a quality signal and this one has earned mine quickly clearly.

Just want to record that this site is entering my regular reading list, and a look at growwithpurpose confirmed it deserves the spot, my regular reading list is short and well curated and adding to it requires meeting a fairly high quality bar that this site has clearly cleared without much effort apparently.

Recommend this to anyone who values clear thinking over flashy presentation, and a stop at draftlake continued in the same understated way, this site has its priorities in the right place which makes it worth supporting through repeat visits and recommendations rather than just one passing read today before moving on quickly elsewhere.
Reading this gave me a small framework I expect to use going forward, and a stop at fashionseasonhub extended that framework, content that produces transferable mental models rather than just specific facts is content with multiplicative value and this site is providing those models at a rate that justifies extra attention from me regularly.

A piece that did not waste any of its substance on sales or promotion, and a look at trendspotmarket continued that pure content focus, sites that resist the urge to monetise every paragraph are increasingly rare and this one has clearly made the editorial choice to keep the writing clean from commercial intrusion which I value highly.
Took my time with this rather than rushing because the writing rewards attention and after grovepassage I had even more to absorb the kind of content that pays back the patient reader rather than punishing them with empty filler is something I look for and rarely find in regular searches lately.
Probably worth setting aside a longer block to read more carefully than I can right now, and a stop at novalog 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.
Appreciated how the writer anticipated the questions a reader might have along the way, and a stop at urbancloverhub continued that thoughtful approach, you can tell when content has been edited with the reader in mind versus just published as a first draft and this is clearly the former approach across what I read.
Thanks for putting in the work to make this approachable, plenty of sites cover the same ground but most do it badly, and a quick visit to fashionlifestylehub confirmed this one stands apart, simple language and useful examples without anyone trying to sell me anything along the way which I really appreciated.
Reading this felt productive in a way most internet reading does not, and a look at globalcraftanddesign continued that productive feeling, sometimes the open web feels like a waste of time but sites like this remind me why I still bother to look around rather than retreating to old reliable sources for everything I need.
The lack of unnecessary jargon made the post accessible without sacrificing accuracy, and a look at globalfashioncollection continued in the same accessible style, technical topics often hide behind specialised vocabulary but here the writer trusts the reader to keep up with plain language and that trust pays off nicely throughout the entire post.
Recommended to anyone working in or curious about this area, the depth and clarity combine well, and a look at riverleafmarket keeps that going across more pages, the kind of site that earns regular visits rather than chasing trends has my respect because it suggests genuine commitment to the topic itself rather than to chasing trends.
Over the course of reading several posts here a pattern of quality has emerged, and a stop at flowlegend confirmed the pattern, the difference between sites that hit quality occasionally and sites that hit it consistently is huge and this site has clearly demonstrated the consistent kind through what I have read this morning.
My reading list is short and selective and this site is now on it, and a stop at pureforeststudio 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.
A clean piece that knew exactly what it wanted to say and said it, and a look at wildhollowdesigns maintained the same clarity of intention, knowing the goal of a piece before writing is something most blog content lacks and the clarity of purpose here shows up in every paragraph for any careful reader to notice.
Now appreciating that the post left me with enough to say in a follow up conversation, and a look at lobbycommune added more material for those follow ups, content that prepares me for related conversations rather than just informing me alone is content with social utility and this site provides that social armament reliably for me.
Now wishing I had found this site sooner, and a look at northernriveroutlet extended that mild regret, the calculation of how many years of good content I missed by not finding the right sources earlier is one I try not to make too often but it does come up sometimes when I find sites this good.
A memorable post for me on a topic I had thought I was tired of, and a look at brighttrailfashion suggested the same site can refresh other tired topics, sites that can revive my interest in subjects I had written off as exhausted are doing rare work and this one is clearly doing that for me today.
Generally I bookmark sparingly to avoid building up a bookmark graveyard but this one earned a permanent slot, and a stop at mossbreeze extended that permanence designation, the few sites I keep permanent bookmarks for are sites I expect to use repeatedly and this one has clearly cleared that expectation bar today.
Bookmarked the page and the homepage too because clearly there is more to explore here, and a quick stop at knackgrove only made that more obvious, this is the kind of place I want to dig through over a weekend rather than rushing through during a coffee break tomorrow morning before getting back to work.
Found the section structure particularly thoughtful, and a stop at modernlivingemporium suggested the same care across the broader site, structural choices guide the reader through the material in ways most people do not consciously notice but feel the absence of when those choices are made carelessly or not at all.
Reading this site over the past week has changed how I evaluate content in this space, and a look at evertrueharbor extended that recalibration, the standards I bring to reading on the topic have shifted upward as a direct result of regular exposure to this kind of work and that shift will outlast any single reading session.
My friends would appreciate a few of these posts and I will be sending links accordingly, and a look at edgedial added more pages to my share queue, content that earns shares to specific people in specific contexts is content with social utility and this site is generating those targeted shares from me consistently lately.
Polished and informative without feeling overproduced, that is the sweet spot, and a look at evercrestwoods hit it again, you can tell when a site has been built with care versus thrown together for the sake of having something to put online and this is clearly the former approach taken by the team.
Refreshing to read something where the words actually mean something instead of filling space, and a stop at draftlog 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.
Vague feelings of recognition kept surfacing as I read because the writing names things I have been thinking, and a look at quillglade produced more of those recognition moments, content that gives shape to private intuitions is content that makes me feel less alone in my own thinking and this site has that effect.
Reading this triggered a small change in how I think about the topic going forward, and a stop at classystyleoutlet 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.
Really clear writing, the kind that makes you want to share the link with someone who has been asking about the topic, and a quick browse through dreamhavenoutlet only made me more sure of that, the information here stays useful long after the first read is done which says a lot.
Decided to subscribe to the RSS feed if there is one and a stop at grovequay confirmed that decision content that I want delivered to me proactively rather than just remembered when I have time is content that has earned a higher level of commitment from me as a reader looking for reliable sources.
Just nice to read something that does not feel like it was assembled from a content brief, and a stop at fashionforfamilies kept that handcrafted feel going, you can tell when a real human with real understanding is behind the words versus a templated piece churned out for an algorithm to find.
Decent post that improved my afternoon a small amount, and a look at trendforless added a bit more to that, sometimes the small wins online add up over time and a useful site like this one is the kind of place that contributes consistently to those small wins for me lately across many different topics I follow.
Now adjusting my expectations upward for the topic based on this post, and a stop at foilcommune continued that bar raising effect, content that resets what I think is possible on a subject is doing real work in shaping my standards and this site is providing those bar raising experiences at a notable rate during sessions.
Decided to set aside time later to read more carefully, and a stop at mountainwildcollective reinforced that decision, content that earns a calendar entry rather than just a passing read is in a different tier altogether and this site is clearly working at that elevated level which I really do appreciate as a reader today.
Without comparing too aggressively to other sources this one stands out for the right reasons, and a look at wildharborattic continued that distinctive quality, content that distinguishes itself through substance rather than style tricks is content with lasting differentiation and this site has clearly chosen substance based differentiation as its core editorial strategy.
Found the section structure particularly thoughtful, and a stop at rarefloraemporium suggested the same care across the broader site, structural choices guide the reader through the material in ways most people do not consciously notice but feel the absence of when those choices are made carelessly or not at all.
Now thinking about this site as a small example of what good independent writing looks like, and a stop at timbercrestgallery continued that exemplary status, the few sites that serve as good examples are sites worth holding up in conversations about quality and this one has earned that exemplary placement through patient consistent effort over time.
Took some notes for a project I am working on, and a stop at mountglade added more raw material to those notes, content that contributes to my own creative work rather than just being interesting in the moment is the kind I value most and the kind I will keep coming back to repeatedly.
Honestly slowed down to read this carefully which is not my default, and a look at knackpact kept me in that careful reading mode, the kind of writing that demands attention by being worth attention is rare in a media environment full of content engineered to be skimmed not read with any real focus today.
Liked the way the post balanced confidence and humility, and a stop at futureforwardclickpinghub 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.
Will be sharing this with a couple of people who care about the topic, and a stop at lobbydawn added more material worth passing along, the kind of site that is generous with quality content and does not make you jump through hoops to access it which is appreciated more than the team probably realises.
Compared to the usual results for this kind of search this site stands well above the average, and a quick visit to edgelibrary kept the standard high, you can tell within seconds whether a site is going to waste your time or actually deliver and this one clearly delivers without any false starts.
