Some techy info in case you're curious.
Icons that are "left out" on the WB backdrop are stored in a file called .backdrop, in the root of the disk that the icon lives on.
.backdrop is just a simple text file containing a list of filenames.
WB reads this when you insert a disk, so if you have a floppy or CD with a .backdrop file on it, the left out icons will appear at the same time as the normal disk icon.
