Hi,

Unfortunately I get this error:

Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__
return self.func(*args)
File "Programming/Gacor/tmp.py", line 83, in newPic
imgPrep.configure(file=os.path.join(imgDir, pics[pic]))
AttributeError: PhotoImage instance has no attribute 'configure'

I think I should mention that I'm completely in the dark when it comes 
to GUI programming (and I don't have much time to learn it... or do I?)

Thanks for the help so far,
Joe
