up at the top, there is a row with a bunch of links, the first one is User CP. Click on that and then on the left there will be a list of things under Control Panel 7th one down is Profile Picture click on that and from there you can either upload it from your computer or copy and paste the URL from your photo hosting site like photobucket.
ya thats where i was before but i dont have a button that says that.. my 7th one down says message tracker.. and the rest of them say nothing about profile picture..??
