Just want to let you know that this feature was implemented and tested.
You can change your Avatar in your Profile section.

Please let me know if you will have any issues with it.

The custom picture is in ToDo list currently and will be implemented soon.
Thanks for reminding actually

I may be missing it, but I can't find where I could put in an image to show next to my user ID. Just show a pic of a bald guy with no image over top of it. Is there a way to put an image in? if not I would much rather have the myibay symbol or nothing there.
