what OS?

Lots of good stuff. I did a google image search for rennsport reunion and told it to only return images larger than 1024x768 and have found a bunch of good stuff. This is a smaller version of one of the good ones.
If you didn't notice, when you click an image (at least for me in Firefox) it's expanding to show a larger version of it. If the version that you see is smaller than you want to use, there is a "More Sizes" link next to the size that will show what other sizes google has found on the net.

If you're using XP, and you've got the Active Desktop on, then maybe instead of the wallpaper, you may be looking at active desktop content.

How to Enable or Disable the Active Desktop

From the Start button, select "Run" and type the following:

%USERPROFILE%\AppData\Roaming\Microsoft\Windows\Th emes\slideshow.ini

It should open the slideshow.ini file in Notepad, and it should be empty. If not, delete all characters in it, save, and reboot.

Windows 7

See above.
Thanks but didn't get anywhere with this.

Was the slideshow.ini file empty?

BTW, the space in the word "Themes" should not be there

OK...got rid of the space and got the note pad up.......it is empty.

Checked on google and not being able to change your wallpaper seems to be common problem in windows 7. The most interesting problem and solution was caused by a monitor display manager. The person reinstalled the monitor display software (samsung) and was able to change their background. Found that fix on tomshardware.com
