Wel u can actually put a image object on the screen and set it's width and height property do the screen size and set tthe top and left property to 0 ,0

Here's a rought example

_Screen.addobject("MyBackground","IMAGE")
With _Screen.MyBackground
.top = 0 
.left = 0
.width = .parent.width
.height = .parent.height
.picture = "MyBackground.JPG" && just any picture file
.stretch = 2 && fit the whole image

EndWith
