Where are the default wallpapers stored?

[rpimps]

If you go to the photos tab and then "Album" and then "Albums" you have a long list of picture folders to look at, one of them is called "wallpaper" and it has some nice wallpapers that are like variations of the default pictures in the "my pictures" folder (the avatar-1 avatar-2 ones etc). But there's no option to set any of them as the wallpaper. Is there any way to do this? If not, does anyone know where in the phone they're stored?

The wallpapers are stored in \Internal Storage\Content\Wallpapers

Thanks a lot.

How do I make any picture in an album my today wallpaper? There's no option when you're viewing the pics to set it.
