Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 155 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

In my SO profile, you may see something odd: a peeking duck.

Peeking duck

I've just recently uploaded this new profile picture of mine. I checked it after the upload and everything's fine. After a few hours, I opened my profile and there it is, the duck has somehow become afraid of the people viewing it.

Is this a bug, a feature, or is it just the duck?

I am about to re-upload my profile pic, but I've decided to drop first this topic to meta.

And if you're curious, here is the original picture.

ADDITIONAL: I've used the non-gravatar way to upload the picture.

ADDITIONAL 2: The problem only shows in the profile view. No problem in chat, less info profile view, and in the questions and answers.

UPDATE: Re-uploaded picture. Status normal (for now, at least).

I've heard of something similar before. Did you use gravatar or the custom upload feature? – ɥʇǝS Feb 7 '13 at 5:15
@Seth Oh, the custom upload feature. – Mark Garcia Feb 7 '13 at 5:16
Could you try using Gravatar instead and see if that fixes it? (Of course this would just be a workaround, not a fix). – ɥʇǝS Feb 7 '13 at 5:16
and if you remove the parameters – Aristos Feb 7 '13 at 5:17
@Aristos So maybe it's a rendering problem? – Mark Garcia Feb 7 '13 at 5:18
@Seth That could ruin the demonstration. Sorry. – Mark Garcia Feb 7 '13 at 5:18
What do you mean? – ɥʇǝS Feb 7 '13 at 5:19
@Seth The workaround may somehow fix the problem, but some may want the actual thing. – Mark Garcia Feb 7 '13 at 5:21
Right. I just wanted to see if that fixed it. Then we'd know if it was a bug for sure. – ɥʇǝS Feb 7 '13 at 5:21
We are looking into this - I should have an answer soon. – Geoff Dalgas Feb 7 '13 at 6:39
Looks like a bug in imgur resize algorithm. Doubt Stack Exchange dev team can do anything (except ask imgur dev team), but curious to see. – Shadow Wizard Feb 7 '13 at 8:13
My profile picture shows the same thing (recently updated on Gravatar) but in my case it's a single grey line at the bottom. – Graham Borland Feb 7 '13 at 9:32
I have pinged imgur and they are still digging. – Geoff Dalgas Feb 18 '13 at 18:03
@Geoff another test case if you like. (original report here) – Shadow Wizard Mar 4 '13 at 20:33

IMGUR has deployed a fix for this.

Here is one. When resized to 128 it's fine. – Shadow Wizard Apr 17 '13 at 12:59
Thanks much, and I will do report gladly any problems. – Mark Garcia Apr 19 '13 at 6:18
Geoff, found other image with that problem. This is the profile. Resized image and full image. Maybe user need to reupload for their fix to catch? – Shadow Wizard May 16 '13 at 23:18
Another broken profile: kunhdapahd, resized image is broken, original is fine. – Martijn Pieters Sep 21 '13 at 13:50
@MartijnPieters thanks - I have reuploaded this and reported this to imgur. – Geoff Dalgas Sep 23 '13 at 4:27
Another one – Shadow Wizard Nov 7 '13 at 11:14
As per your request; this is happening again: User profile picture not rendering correctly – Richard Tingle Feb 25 '14 at 0:54
Another one: Why is David's profile image corrupted? – Martijn Pieters Sep 1 '14 at 17:15
Another one: Profile picture is not showing up properly – Martijn Pieters Nov 3 '14 at 18:57
"Please let me know if you find any other images that have this artifact" - any reason for this sentence if you're ignoring all the comments saying "yes it still happens"? Going to edit it out to prevent others wasting their time. – Shadow Wizard Jan 3 at 21:30

Unlike what Geoff said in this answer, this has never been fixed.

To this day, certain thumbnails (imgur pictures with a fixed size) are corrupted randomly

Few examples:

The only way to fix it I know of, is to re-upload the picture again, which cause new thumbnail creation process.

Thanks @rand and congrats for becoming a mod! (never noticed before. :)) – Shadow Wizard Mar 14 at 15:12
Thanks! :-) Wow, you missed that fun? It was ... an extremely controversial election. – rand al'thor Mar 14 at 15:16
I only saw parts of what was going on here on MSE (including the chat room about you) and tried to stay away. Glad it's all sorted out by now. :-) – Shadow Wizard Mar 14 at 15:17
Heh, I won't provide you with links to the controversy then ;-) (Btw, I'm surprised to see you're not a mod - I was sure you were, and almost said "see you in TL". Did you use to be one?) – rand al'thor Mar 14 at 15:19
@rand not here, in a different place, years ago... – Shadow Wizard Mar 14 at 15:24
