Avatar problem

I tried to change my avatar several times today and now it is not showing at all. I'm using Firefox so I tried "View Pic"" and I got this message: The image “http://www.whatboyswant.com/SharedImages/UserAvatars/50013.JPG” cannot be displayed, because it contains errors.

You have uploaded a broken image?

hmmm, it is the same that i was using before. so i don't think is broken.

Maybe webspace problem
