Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 129 Stack Exchange communities.

I don’t know if this is a bug or is this how the images work, hosted on imgur. It basically adds a query string. I added a profile pic as gif but it doesn’t work as how gif images work. If I goto the image url it works fine.

My Profile: http://stackoverflow.com/users/724764/defau1t

Image URL on profile: http://i.stack.imgur.com/QcPvr.gif?s=128&g=1

Actual animated image Url without Query String (working): http://i.stack.imgur.com/QcPvr.gif

Is this how images hosted on imgur work or is this something else?

I am glad it doesn't work on the profile page and URL. –  Oded Jan 17 '13 at 14:58
    
imgur doesn't support animation when it resize the image on the fly. –  Shadow Wizard Jan 17 '13 at 15:01

So your bug report is "it's not animated"? I'd call that a "feature". Not nauseating your users (or not allowing users to post animated content) is a definite plus (especially in a professional setting). I assume you can't use an animated Gravatar either, so that should have stayed the same. –  Joachim Sauer Jan 17 '13 at 15:02
    
possible duplicate of Profile picture cannot have transparent background –  Shadow Wizard Jan 17 '13 at 15:02
    
Dupe because both animation and transparency are image features that are not preserved when imgur is resizing the image. –  Shadow Wizard Jan 17 '13 at 15:03
    
@ShaWizDowArd: agreed, but then again: one of those I'd like to see fixed. The other ... not so much. And I think big parts of the community would agree. –  Joachim Sauer Jan 17 '13 at 15:04

but gif images and transparent pngs are all together different stories. they dont fall in one line. I think it is actually the aspect as how imgur treats images. –  anon Jan 17 '13 at 15:06
    
@Joachim Gravatar are smarter: they convert any image to PNG prior to saving in their server, while imgur save the original image as-is without ever touching it. PNG allow transparency but not animation, hence the behavior we're so used to. –  Shadow Wizard Jan 17 '13 at 15:07

Please tell me you're only trying this out as a 'proof of concept', and you don't really want an animated brain-ache image as your profile pic? –  JonW Jan 17 '13 at 15:16

+1 for trying to test. I'd +100 if I could because your test shows that animation is blocked (quite a relief) –  gnat Jan 17 '13 at 15:18

@Anna I won't call it by design. The ?s=[number here] wasn't added to the profile pictures URL to block animation but to preserve bandwidth and improve the speed. Blocking animation is just a side effect, and for all we know imgur might decide one day to support animation when resizing their images. This is by-design on imgur side. :) –  Shadow Wizard Jan 17 '13 at 15:35

@ShaWizDowArd No, disabling animation is very much by design on our side. –  Anna Lear Jan 17 '13 at 15:36

@ShaWizDowArd Okay, let me spell this out. Disabling animation in profile pictures even if you uploaded an animated gif is by design. If Imgur fixes their resizing so that it lets animations through, we'll have to find another way to disable them. See Tim Stone's answer on this question as well. –  Anna Lear Jan 17 '13 at 15:40

This is not a dupe. –  Lance Roberts Jan 17 '13 at 15:41

@refhat It happens; there's even a badge for it. In this case, people clearly disagreed with the idea that animated gifs should exist; hence, down voting your question, and up voting the answer. Makes perfect sense. –  Andrew Barber Jan 17 '13 at 20:13

It doesn't animate because allowing it to do so would be super annoying.

A few days ago, uploading an animated gif would work as you were expecting it to, but that was considered a bug and was fixed, making this :

I'm afraid we're not going to support animated gifs. The ability to upload them was a bug that has been fixed

IT WOULD SO NOT BE SUPER ANNOYING –  Pëkka Jan 20 '13 at 18:56
    
You didn't put your all-caps link in italic-bold, I am not fazed. –  Tim Stone Jan 20 '13 at 19:00
    
Crap, it's too late to edit. I'll have to flag for a moderator to do it for me. I WILL FAZE YOU YET! –  Pëkka Jan 20 '13 at 19:02
    
I wonder whether it's possible to create a GIF header that passes Stack Exchange's filters but causes a browser's sloppy image library to render an animation. Probably the only reason to delve into the GIF format spec in 2013! –  Pëkka Jan 20 '13 at 19:04
    
I think they're relying on the fact that a gif image requested with a size parameter from imgur will actually be sent back as a jpeg of the appropriate size, so I think you're out of luck on that one :P –  Tim Stone Jan 20 '13 at 19:15
    
I wondered about doing something similar with PNG/MNG... –  uɐɯsO uɐɥʇɐN Apr 22 '13 at 23:00
    
Forget that - apparently the g=1 query string parameter prevents this from working. But I came pretty close :P –  uɐɯsO uɐɥʇɐN Apr 22 '13 at 23:51
