I copied a jpeg picture in the Windows\Web\Wallpaper folder and want to make it the Desktop Theme. I right-clicked on the Desktop and selected Personalize. I then selected Desktop Background. For Picture Location I selected Windows Wallpaper. The picture appears in the window. I selected the picture and clicked OK. However, the picture does not appear as the Desktop Theme. I went through this process a number of times, selecting the same picture, as well as different pictures in the Wallpaper folder, with the same result. For the record, I am able to change the Desktop Theme color. The computer is a very basic model: Compac Celeron 3.2G running Windows Vista Basic with 512mb. Can anyone offer a solution?
