Windows Wallpaper help

Im trying to add a folder containing .jpg files to the default list of windows desktop wallpapers and i can't figure out how.

if you set the picture as your wallpaper, it should then show up in the list

yea, but it goes away after you change it and its not for my computer its for a computer im working on.

put the image in the c:\windows\web\wallpaper directory, and it should show up on the list permanently

thanks, that worked perfectly
