I'm not sure either -- changed mine so long ago I forgot how I did it. Try going to the My Pages tab above, then My Account, then the Edit tab. You get an example of the post form (like this one) with choices. One says "Insert Item." Try clicking on that & see if it guides you to upload your avatar.
If that doesn't work, you can ask admin -- back to My Pages & the scroll down list has "Contact US." Weird, it was easy when I did it a couple years ago. Good luck!
