How do I delete the pictures, in my list for desktop backgrounds?

When I right click on desk top, go to properties, and then click the desktop tab. Then it says background, and has a list of pictures, most of which are ones that came on the computer. How do I delete those pictures, and what not?

The name of it is simply listed as “1”, but when I search for a file named that it doesn’t come up. You know what I mean, instead of some of the others named stuff like Autum and what not, this one is listed as “1”.

Please help me, thanks!

If you’re using Windows, check in your c:\Windows directory for a “1.bmp”. That’s usually where most of the background pictures are located.
