In the bottom row of images left click on the image marked desltop background. Use the browse button to locate the picture you want and select it.
I have just bought a Samsung Netbook running Windows 7 Basic.
So far I have not found a way of replacing the rather boring plain blue desktop background with something more interesting, like one of my own pictures. It is quite simple to do on XP and Vista.
Can it be done please? Any help appreciated
