On the right-hand side, under "My Profile" click on "Update Profile." There's a tab on that page that says "Avatar."
OT, I saw the movie in 3D. It is a pretty good movie, with superb effects. It may be, after all these years, that 3D movies have finally moved out of the "gimmick" stage. And the movie industry may have found a way to get people away from their big-screen home TVs and back to the theaters.
It takes an iron man to play with a toy iron horse.
Thanks for responding to Bob, Mr. B.
Yes, it is under "Update Profile" in the right sidebar, click on the avatar tab, and then fill in the fields that apply. You should be able to upload a small file directly from your PC.
Bob, don't forget, once you are all set to leave that page, that you must scroll down to the bottom and actually save the changes you have made to what existed.
I find the server makes the adjustment fairly soon afterwards, often within a few seconds.
