I think I got you on that.

re that's why overriding paint or paintComponent will work
Should I be using the super() method call in there?  If I do will it
overright my image?  If I don't will it leave my current image there?  I
seem to remember reading something about that in my Deitel and Deitel book,
but it was a long time ago.

Thank you for your patience and ideas! :>
