the best way is to go to your profile, minimize the page open up the internet, go to google and search for whatever you want, go to small pictures, right click on the picture you want(must be 100x100 pixels, .jpn or .png,and must be 7kb) go to save picture as..., and then come back to your profile, click on Browse and select your picture. It will tell you if it loaded right.
