I am working on a script to find bad image files. I am using PIL

deal with the exception.
Currently my code is basically
try:
     im = Image.open(ifile)
     try:
         print(im.verify())
     except:
         print('Pil image.verify() failed: ' + afile)
except IOError:
     print('PIL cannot identify image file: ' + afile)
except:
     print(ifile)
     print("Unexpected error doing PIL.Image.open():", sys.exc_info()[0])
     raise

You've already had some advice so I'll just point out that a bare except 
is a bad idea as you wouldn't even be able to catch a user interrupt. 
Try (groan!) catching StandardError instead.
