As I was looking at this answer on SO mobile site on my iPhone, an animated profile picture caught my attention.

Animated gifs are not allowed on profile pictures, but this one managed to show up on the mobile site.

@Lix Also on every desktop browser, just click "mobile" at the footer. – Antony Apr 21 '13 at 16:26
It seems only power of 2 scales actually work and "disable" the animation. The used 30 scale does not seem to be doing much. – Bart Apr 21 '13 at 16:36
Oh, the infamous "something's wrong but we have no idea what" tag. But really, based on the URLs, this looks like it might be a problem with Imgur not processing images correctly. – animuson Apr 21 '13 at 16:44
@animuson Certain numbers have an effect on scaling and animation, e.g. 16, 24, 32, 48, 64 and 128 – Antony Apr 21 '13 at 16:46
@Antony: From the looks of it, those are the only sizes you can even request to begin with (all others just return the image). Perhaps we're just trying to transfer our Gravatar size expectations over to Imgur? – animuson Apr 21 '13 at 16:49

We had IMGUR fix the "glitch" - you shouldn't see animated image any more on mobile.

Interesting, they had white list of allowed sizes? – Shadow Wizard Apr 22 '13 at 23:26
