You can use tinypic.com, photobucket.com, or any other image host out there. :D
No no Heather!! I mean in the BB profile!! I don't know where it says in the Beyond Beautiful change avatar or something like that!!
Click "User Control Panel" on the top right, just under the banner. On the left, click "Edit Avatar". Upload your avatar (max size is 125 x 125) to an image host such as imgur.com. Then paste the direct url into the "Link off-site" box, clear the avatar dimension fields and "Submit".
