GIF image not rendered in Safari 5.1
Does work in IE, FF, Chrome and Opera, but also in Safari 5.0.2. Regression bug?
Did you test Safari 5.1 on Lion or Windows?
This image fails to open in Lion Preview.app, meaning that this is not a WebKit bug, but an issue in lower level system frameworks. I'll file a bug for Apple engineers working on that framework to investigate.
Marking INVALID as a non-WebKit issue, but thank you for reporting this!
The image also doesn't render in Safari Mobile on iOS 4.3.5. Looks like that lib/framework is also used there.
Does happen on Windows XP and OSX Lion with Safari 5.1.
