Avatar Fail

I can't change my avatar. Help!
What are you trying to use?
Another image file....this one in fact.


But it won't let me use it, it just resizes my current avatar. Same as if I try other image files.
Well, I don't know how you messed it up, but I went ahead and changed it for you.
Thanks.....wait how is that my fault?
Well, I assume that since everyone else can use it fine, that you must have done something wrong. Some stray something or other.

Next time, try to completely clear out the avatar, then reupload it.
I did that.
