the example on that page attaches the image to a widget instance,
not a canvas object handle (which is an integer; unlike user-defined
classes, integers don't allow you to attach arbitrary attributes to
them).

if you just want to display a single image, just attach it to self:

    BackgroundFile = PhotoImage(file="Background.GIF")
    Background = self.MainFrame.create_image(0, 0, image=BackgroundFile)
    self.image = BackgroundFile # keep a reference!

if you want to display multiple images on the canvas, use a dictionary
or a list to hold active image references.
