when you right click a picture, I'm aware of an option to "save image as" and "use image as desktop picture", but i'm not familiar with an option to "save image as desktop wallpaper"... are you sure that's the correct wording of the option?
I would think he would be better off asking where the desktop photo file is saved. Or, even better, he could search around the filesystem on his Mac himself.
When you right click and choose "Use Image as Wallpaper" it doesn't get saved anywhere. It's just used as your wallpaper. Once you change the wallpaper you can't go back into system preferences and choose it again. It sort of goes into the clipboard.
