This is more of a GUI question, not an applet question, so I'm moving it to our AWT/Swing/GUI forum. Please find the thread there and continue the discussion.

I would define a component to have an image and a rectangle, and have its paintComponent method render them both. To cause the rectangle to disappear set it to null:
