1) for starters, remember to lock down the picture handle before you draw.
(Yes, Virginia, DrawPicture does move memory).  

2) Are you *sure* that the rectangle is the same size as the picFrame
rectangle?

3) If you haven't got enough memory, the picture won't load in.  This will
give you a nil handle, which you should check for.
