Unable to repro this issue on MAC (10.11.6) for Google Chrome Stable Version - 52.0.2743.116

Screen-recording is attached.

@inian1234: Could you please re-test the same on a clean profile [chrome://settings -> Add Person -> Do not login] and let us know your observations.

Also, update your Google Chrome to Latest Stable Version - 52.0.2743.116

Thank you.

Hey,

The image is rendering - just not progressively (layer by layer instead of top down). In this video I just made, the HTML page on the left renders it progressively, but when I open the same image referenced in the HTML page, it loads sequentially. (Ignore the page on the right half of the video)

Confirmed in M52 stable and M54 canary on macOS.

Back looking at this on a slow network, cache cleared etc. Reproduces for sure.

I think that the difference between using it in am img tag and loading directly is that direct display of images resizes the image to fit in the viewport, whereas using it in an img tag uses the native size if none is given. To resize we probably need the complete image loaded before we display anything, hence bypassing the progressive nature of it.

inian1234@, could you do one or both of the following for us to confirm the hypothesis:
(a) try this with an image small enough to fit in the window without resizing and/or
(b) see what happens when you use the existing image but give a size for the div that forces the image to resize (or use it as background image with background-size: cover or the like).

As far as fixing it goes, all I can think to do is emit an image when each layer is decoded, but that seems complicated.

I created a page with progressive images small enough to fit the viewport (so that no re-sizing happens). However, I am still seeing the same issue..

Thanks for the new content. I'll route this to engineers with more experience in this area.

Oops, should have archived the pages that are now gone.

Hey schenney, sorry I didn't realise that I brought down the server. 

I can re-create the progressive versions of some image and upload it again on a server if it helps. 

If you are able to just attach one of the (progressive) images to this bug, that would probably be fine too.

Still missing reproduction images. Re-open the bug if they become available.

@schenney@chromium.org Pretty sure this is a dupe of https://bugs.chromium.org/p/chromium/issues/detail?id=884959, so it's already fixed.

Yup, confirmed with a progressive image (https://s3.amazonaws.com/inian-backup/ini1.jpg) that is rendering as expected when opened directly too.
