I just visited my Area51 account and noticed that my profile picture is not the same as on all other sites.
Accrording to this recent post the image will be synchronized when synchronizing the complete profile. I did that but the image is still the same.
Then I wanted to change the image in the Area51 profile directly - but I can only change to a gravatar image and can't use the new and fancy Stack Exchange image.
Is that a bug?
