how do i change background?

it has to be 300X170

With PSPersonalize, yes, resolution matters, but with ThemePSP, not only is it easy to put on but the size of the pic doesnt even matter!

YES ok thats good ty so what program do i use to put it on?

X-Flash you can even throw in Hi-Res Pics!

ok on x-flash it says replace jan-feb-mar-apr ...etc how do i make it to where its my pic im replacing instead of some gay rainbow or something that comes on it

change the pic in the modified folder

ok done :) i used pspersonalize
