vB4 need some styles help or point me in the right direction
 

So I upgraded to VB4.0 - Yayyyy !! it went well and no major issues minus the mods and hacks I had installed ..

So i bought a skin to use while our ones are updated and tweaked to work with vb 40

Here is the link http://www.rk1gaming.net/forum/forum.php

If you see the background the soldier ... well the skin comes with like 17 different ones to use. What I would like to do is have the background change based on the day of the week.

So Monday you would see the soldier
Tuesday you would see , Halo
Wed .... WoW

any thoughts on how you could do that ... any help would be appreciated
