Upload some icons on to photobucket and then, get the link off them, and in the headder section of preferences... type But change ' URL of graphic' to the url of the photo... but you gotta enter the code for as many icons as you'd like.

If you ain't got a photobucket account... it's www.photobucket.com and just sign up. Remember to upload the icons on there though.

Hope it helps
