Tkinter Bitmap Newbie question

Thanks for all reactions. I can load the bitmap now thanks to your help.

But just to make sure I'm on the right track,
- Is XBM the best way to for bitmaps? The ones I saw so far are all black 
and white. Do they also exist in color?
- Is XBM also the best format for glyphs on the Windows platform? Or would 
'Images' of a different format be nicer?
- Does someone know of a nice downloadable collection of standard glyphs 
(Bitmaps for Open file, New file, Save file, ...) with a free license?

Thanks again,
