Okay Eagle
Go to the edit avatar Page. Leave the top circle in use avatar unchecked (blank).
Then go to the bottom section - under all the cool pics and you will see the area where you can put your picture.
Click in custom Avatar, select browse, go to your own file at the top of your computer and pull your avatar from that. (Make sure the avatar that you want to use has already been saved in your own computer files and then highlight it). Make sure the name of that picture is listed in the long box. Then update it at the bottom of the page.
It took me a couple of goes to work it out. Good luck Eagle
