Help with windows live messenger ?

[Pc_Pimp]

I know you can change the background of a conversation box, but is there some way you can change the background of the main windows live messenger screen, the one with your contacts list and everything? Is there some program file i can modify or anything to be able to use a picture as my background for the main messenger screen ? thanks
