In the Display Properties section , under desjtop it will list several backgrounds. My question is: how do I add more choices .I have tried but don't really know the steps. I wind up with ths item on background and not in the display listing. Thank you Ann

Instead of "adding more choices" what you can do is simply get a picture that you want as a background, and the right click on the picture icon itself, and it will give you a choice to "Set as desktop background"
