first go into your profile. at the top of the page hit edit options. in the options page scroll down to the bottom, the last item on the list is called Avatar. click on change avatar. you then follow the intrsuctions they give you. you can either choose one of the selections that are offered or you can import one of your own pictures from the browse feature. i hope this helps, i kind of figured it out for myself by trial and error. if you have any questions just let me know, or if there is anyone else out there that could explain this better please feel free to help me out. Good luck, i hope this helped.
