What's going on here, then ...

have you logged out and logged back in...sometimes that does it... and have you actually gone to your profile like other people do, not just to the "add/change profile" and "add/change picture"?

those are my only suggestions.... if that still doesn't help, then I'd send Janis a private message.

I don't know what to tell you... :( There is nothing I can actually do, other than suggest to re-upload the picture you want.

You could also try emptying your internet temp files....

If nothing works, it really is no problem for you to send Janis a private message explaining your problem.
