Uploading picture to profile - problems

Hello, I’m trying to add my picture to my profile and not having much luck. I can browse and select a file (under 500 kb in size) but after it says the upload is complete, I don’t see anything in either of the two windows. If I click on ‘Finish’ I get I am using an error message (500 server error or something like that) mac with OSX 10.3.9 and my browser is firefox Am I just too outdated for this feature to work? Any help would be appreciated!

Also as I am trying to spell check this post, I am getting a ‘server error’ message as well so please excuse any sp’s…
