(it's free)Find the avatar you want. Right click on the avatar and do a save as to a file in your computer. (My Documents/My Pictures/Avatars for example). Log into photobucket. You will be on a page that says upload. Click Browse, find the avatar you want in your computer and double click the picture. Click upload. After it has been uploaded you have 3 options to copy. I copy the image option, then paste it in the line for the avatar.
