I cannot get pictures on the desktop. I am able to change backgrounds, but when I select a picture and I see the picture in the preview window, selecting "set desktop" does nothing. I am running System 8.0 on a PowerMac 5400/180. I've tried replacing the desktop pictures control panel with the desktop pictures control panel from my PowerMac 7200. No change on my 5400. I met my wife in Glacier Nat'l Park, and I want that picture!
