Mergatroyd,
- Go to "Edit Your Profile" which is under "Hub Controls" or just go here: http://www.agoracom.com/members/Merg...
- Hit the Browse button and look for the picture on your computer (it probably has to be in .jpg, .bmp or .gif format)
- Once selected, hit the "Update" button at the bottom of that screen.
Cheers,
