Instructions for using Weather Backdrop replacement tiles:

1. Go the the following folder-- C:\Program Files\Stardock\ObjectDock\Docklets\Weather
2. Back-up the file called "backdrop.png". I recommend copying them into your documents folder,  in a place where they won't get lost--just in case.
3. Copy the enclosed backdrop file into the above directory, replacing the original images.

Now try mousing over your weather docklet on your dock, and watch what happens... :)
