Yes, I know.  The call to BitmapImage() works fine, the error occurs when I
try to use the bitmap in a button like:

   Button(root, bitmap='queen')

This is where the error occurs -- it doesn't matter if I use the name I
specified in the call to BitmapImage or let Tk generate one and retrieve it
with str().  What I can't figure out is how to use bobpic as the bitmap for
a Button.
