I downloaded the program to make a tray icon, which is 16 X 16 and 16 colors, however, I couln't figure it out how. please, let me know. thanks.
tray icons are icon shown in the right lower corner of the screen and they can have any color depth supported by the OS, not just 16 colors.
If you need help, please describe your problem in more detail. I have no idea what you are trying to accomplish.
