Back in the days of slow internet access, nearly every non-animated image was a jpg and loading from blurry to clear was the norm. It's part of the file format.

- mark-r 9y agoThe idea was that you'd see the image get progressively better as each pass was completed, thus the term "progressive". But in practice the browsers decided not to display anything until the image was finished loading anyway.
- sp332 9y agoI don't think this is right. IE9 renders progressive JPEGs progressively. https://calendar.perfplanet.com/2012/progressive-jpegs-a-new-best-practice/ https://calendar.perfplanet.com/2012/progressive-jpegs-a-new...
- mark-r 9y agoIt appears the situation isn't static, thanks for the link! It would have been interesting to see older versions of Chrome and Firefox tested too - I'm wondering now if my recollections are faulty.
- cpeterso 9y agoThis site simulates a slow download of a progressive JPEG so you can test how your browser renders them. The page is from 2007 so its claim that IE doesn't render them progressively appears to be out of date. http://pooyak.com/p/progjpeg/ http://pooyak.com/p/progjpeg/
- khedoros1 9y agoI clearly remember watching the image clarity crawling down photos on dial-up. Otherwise, you'd be staring at a blank screen for 2 minutes, instead of a gradually-improving image. (Since you mentioned Chrome and Firefox in another comment, I'm not thinking of browsers that new).
- jschwartzi 9y agoNetscape Navigator certainly did this. IE did too, I recall.
