DropDesktop - Change Desktop wallpaper by drag and drop
Version: 1.0DropDesktop is a applescript droplet that lets you change or cycle through supported desktop wallpaper files.
Operating System: Mac OS X
You can either drop a single or multiple images onto the droplet. It will then cycle through them with 2 second intervals and leave the desktop wallpaper as the last image in the selection.
In case you only drop just one image, DropDesktop will set it as the desktop wallpaper.
