Wallpaper Picker Description:

Build up a collection of
Wallpaper Bitmaps in a single folder, and have the 'Picker choose one at
random at startup to use as wallpaper. Also, whenever you feel a change of
mood is needed, simply click the smiley icon on your taksbar's system tray,
and get a different randomly-chosen wallpaper! Now supports tiling and
centering - WPP remembers the center/tile setting for each file, so when
it's picked at random, it'll be displayed properly. Quick, intuitive and
simple!
