I suggest using the background color that I'm using for the Serena Wallpaper. It's better to use the larger Venus picture for your Wallpaper if you have a 15"+ Monitor.
Wallpaper instructions
1: Assuming your using Windows 95
2: Put the mouse pointer on the picture you desire then press the right mouse botton.
3: A whole bunch of crap will come up and all you need to do is select "set as wallpaper"
4: That's all there is to do
