Perhaps someone out there would like to give me some pointers?
TOC, copy the address of the pic you want as avatar. Go to 'My profile' - 'View/Update Profile'.
In 'Avatar Image' click in 'Select a different Avatar Image'.
In 'Use Custom URL' paste the address of the pic and click in 'Set URL'. Finally, click in 'Update profile'. It's ready.
I don't know if I made myself understood, but I hope this help.
