pkasting: I haven't been following changes to image decoding recently. Have you made 
changes that could've caused this regression or do you know who has?

In the newest version 3.0.190.1 Animated Gifs do not work anymore. Was working in the 
previous version for me.

 Issue 15362  has been merged into this issue.

The decoder code I work on is os-agnostic.  Nothing I can think of would break linux and not windows.  
My first suspicion is to look elsewhere, e.g. at the painting functions or something else platform-
specific.

Note that I am on vacation for two weeks so if you want this fixed before mid July someone else will 
have to try to track it down.

Just to say this bug is also happening on Windows (at least Windows 7 RC x64, which I 
run).

Confirmed on Vista SP1 + Chrome

When I open the animated GIF (which doesn't move) in a new tab, the following message 
is logged:
- Resource interpreted as document but transferred with MIME type image/gif. 

As I reported on another bug report, this bug affects Chromium on windows XP SP3, since 
at least, build 18881, when I first noticed it. So it is most likely a flaw in the code 
that displays gifs rather than in anything platform specific.

Maybe it's time to switch to one of the animated png formats?

animated png would be nice to have, but the majority of the web sites uses gif as 
reference format for animation, so I think we should fix the bug.

Assigning to brettw, who knows this code a bit. 

Check WebKit trunk to see if the problem repros there.

The problem is GIFImageDecoder.repititionCount doesn't have const so it doesn't match 
the superclass and the image is not overridden.

Upstream bug: https://bugs.webkit.org/show_bug.cgi?id=26759

Confirmed.

Windows 7 RC x64
Google Chrome	3.0.190.1 (Official Build 19007)
WebKit	531.0
V8	1.2.8.2

Checked in upstream in r45293. Should be fixed in the next merge, leaving open until 
that happens.

My Chrome updated to version 3.0.190.4, however, animations still do not work.

Chrome 3.0.190.4
GIF is frozen, nothing moving

Animated gifs used by site www.wunderground.com do not move. Version 3.0.194.4

they started to work on this bug and is absolutely useless if everyone comments 
"Animated gifs on site xyz.com doesn't work".

remember that the dev version are not tested and maybe instable. if you don't want to 
accept that features break you should use a more stable version like Beta.

Same problem.
Animated gif are frozen.

Problem solved in version 3.0.191.0 (19540) 29-Jun-2009 15:43

Ubuntu Linux 9.04

The merge with the fix landed in r19457.

Looks like that upstream revision was merged (or a hotfix introduced) sometime today.

Confirmed working

3.0.191.0 (Developer Build 19540) / Windows 7 RC

Confirmed working on XP SP3 as of version 3.0.191.0 (19540).

Apparently some say it is working and some say it is not..can't confirm at this point 
because I don't have it yet.

Gifs are animated properly using the 3.0.193.0 (20009) build. So it's not a regression 
with recent code. All of the recent duplicates (see comments 45-47) are using builds 
that were affected by the bad webkit code, so maybe they need to update to more recent 
builds. Hmmm?

I liked it much more when animated GIFs didn't animate :((. Will it be possible at 
least to turn animation off?

Working correctly for me using 3.0.191.3 Dev channel build, on Windows 7.  Tested using 
URL reported not to be working in comment #48.

Working correct for me too on 3.0.191.3 on vista.

Not working correctly for me - there is a delay before they run - I'm using windows XP, 
SP3.
Same as vhanla on the 3.0.191.3 blog post 
(http://googlechromereleases.blogspot.com/2009/07/dev-update-animated-gif-fix.html)

Works great on 3.0.192.1 and Windows 7 Build 7100 x86.

error dev ver.
