If memory serves me in OS 3.1 you need to have a program like Art Department Pro. or I beleave Delux Paint as the picture must be in an IFF format in order to use as an icon image. In OS 3.5 and 3.9 there are built in programs that alow this. I use the Video Toaster to do all my Icons as I can tell it to save a picture as a 256 colour icon image.
