Interesting, Gretchen. When I tried the first couple times, I had actually (coincidentally) already changed my birthdate to the correct date before I tried to update my picture, and it still wasn't working - but I didn't try to fill in all the other fields too (I don't want my last name on my profile).

HOWEVER - when I signed in today using Safari & Chrome it shows my profile picture updated - but still shows the old one if I use Firefox. Hmm...
