I don't think there is a way to do this easily (without manually comparing
the pixels), because although the two pictures might look the same,
they are two different objects. The '=' operator is not defined for
Images, and the 'Is' operator will not do what you need in this case
(because they are two seperate objects, not two seperate references
to the same object).
If you tell me what you are trying to do in this program, I might be able
to help you come up with a better way than comparing the pictures
in the picturebox.
