<snip> Problem solved...I tried James' suggestion (explicitly instantiating the root Tk window, and then running the mainloop() as suggested), but it produced the same result i.e. no photo. Ugghhhh... I then looked REALLY closely at my code and noticed that my __init__ function was actually ___init___ (3 underscores instead of 2). Thus, a Frame object was being built, but the __init__ function wasn't getting run. So no image was ever getting added. Silly underscores...or, silly Python newbie :-) It now works under both Linux and Windoze just fine. I would have thought that having no __init__ function would flag an error, but I guess this isn't necessary. I thought about grabbing PDB to debug, and I bet this would have shown the error immediately (i.e., it would never have called the function). Being a newbie is such a joy...
