John, just download the picture you want to your photobucket and use the Direct Link code under that picture(should look like this http://i72.photobucket.com/albums/i176/cjpunish/DSCF2193.jpg) and go to your settings page and click on the Profile tab and click on the change avatar tab, then you should have 3 boxes you can type in, you can either upload from your computer, has to be a certain size though, you can use a web link (URL), don't even worry about the 3 line. Go back and copy the direct link and past it into the URL box and hit save changes at the bottom.
