I loaded my picture to Photobucket, then copied the link code and entered it into the appropriate spot in the avatars list.
1. go to the link Profile (At the top) - enter your password
2. After loading your image to Photobucket and copying the link text (will look like http://photobucketxxxx.xxx.xxx or something like that)
3. Select "Submit Avatar" in the profile screen
4. Paste your photobucket text
5. Name your Avatar
I am not POSITIVE this is how it is done, but pretty sure. One thing, make sure you have the image the size you want it. If your image is larger than what shows on the screen, the browser will resize it for you...and it doesn't do a very good job. [;)]
6. Select "Submit"
