To change your picture, directly below where your picture would be
(left side of the page), there is a link to click change "My Photo".
(Or you can click "my settings" and make sure you are in the "account"
section). Next to "profile photo" there is a button with a small green
and blue square. Click the button, and it gives you the option to use
an existing photo (from photos you have uploaded) or upload a picture
from your computer. To upload a photo from your computer, click
"browse" and it will open a window to find the picture on your
computer. Once you have found the picture and clicked the appropriate
buttons on that window, click "done". When you have the picture you
want set, make sure you click "save" or your picture will not be
changed to what you want.
