I dont quite understand what you mean. Are you looking for the directories where the screensavers and backgrounds are? for screensavers, they run like applications, not images, and windows wallpapers are usually stored in C:\WINDOWS\Web\Wallpaper as far as I know also you could read this http://www.skinz.org/screensavers-articles/Windows-Screensavers-Explained.html Hope that helps.
Thanks Kuze, I guess I should have asked it this way. I have a picture that I took on my camera and used it for wallpaper. The problem is I never put it on a disc and now it got deleated from my memory card. Any chance Of finding it on the computer as wallpaper to put on a disc? thanks !
