We should run the icons we host through a lossless optimizer like pngcrush to get smaller file sizes. We already resize them in a task, so it could be done asynchronously pretty easily. We won't get huge wins - probably less than 10%, every byte counts!

What was your command line. There are lots of options. Some don't make a difference.

I had tested with optipng with -o7. Here are my results for a new attempt at crushing all 35 64x64 icons from /fireplace/search/featured/ API endpoint for region "us" (we don't necessarily load them all by default, especially on mobile, but this was just a quick and dirty test): Originals: 328K Using pngcrush -rem alla -brute -reduce: 292K Using optipng -o7: 316K

Giving bug to :nearlyfreeapps since he mentioned on IRC he wanted to take a look. Note: it would be interesting to do the same thing for previews as well, but let's keep things simple and start with icons first.

Fixed in https://github.com/mozilla/zamboni/commit/ac35b14438914f27026bf27e71afdac6e9c87bf8 STR: - Upload an app, make icon submission and edit still work and that the icon displayed in consumer pages and developer pages once the app is approved is not altered. (we'll verify that the size reduction is working properly ourselves)

I have submitted a new app with an icon, and then changed the icon twice in the Edit Listing page. In consumer pages, the icon displayed is the second uploaded icon, and not the actual icon. Please see screencast http://screencast.com/t/FGGkpZhIZ

I see yet another icon (a red car) when I go to your app now : https://marketplace.allizom.org/app/test-app-icon ; does that mean that it eventually updated ?

No, that's the last icon I have uploaded, but this is what I see in consumer pages http://screencast.com/t/iATfmIEMw

Closing since the icon eventually appeared. Stage and dev have both been having issues which we believe would be solved by bug 987927.

Verified as fixed in https://marketplace-dev.allizom.org/ on FF29 (Win 7). Postfix screencast http://screencast.com/t/ZzSXwsZt9 Closing bug.
