Add icon to new Launch Menu item?

I can add a new launch menu item simply by creating a .tgt file and saving it in the applicable directory under /etc/photon/launchmenu, but how do I add an icon to the new Launch Menu entry?

Add line to .tgt file (substituting your path and icon filename):

sicon = /directory/subdirectory/icon.gif

Icon file should be 16 x 16 pixel GIF for normal Launch Menu view.

Cool! Thanks.
