I think it is still not working...
If you make it small enough it will work
Yours works if I open it in another tab. So I think the avatar resizer is still getting you. I don't know what the max avatar size is.
There is also a file size restriction, set by admin. Yours is a photo with lots of frames so it could be too large file size. Just guessin..http://www.simplemachines.org/community/index.php?topic=354497.0
