The default crap gallery displays images at 16bit color, and therefore creates wallpaper in 16bit color.

Multi Touch Gallery (free) displays images at 24bit color, but uses the default image gallery application for setting wallpaper. So I get 16bit for wallpaper.

Is there either a great image gallery app that displays and sets images at 24bit color, OR...

The wallpaper app (not image gallery wallpaper setter) actually displays images and sets wallpaper at 24bit color. So I was thinking, if i could find the folder where the default wallpapers are located, copy some images to that folder, then the wallpaper app would display and set them at 24bit for wallpapers. What folder are the default wallpaper images(galaxy, grass, san fran bridge, desert, etc) located in? I can't find them
