The PIL show() method looks for the default viewer. How do I change this to a different viewer (of my choice)?

You probably shouldn't be using PIL at all then. Why open the file in
Python just to export it and re-open it in an image viewer? It would
be simpler just to point whichever image viewer you prefer at the
original file directly. Your entire script could just be something
like this:

import subprocess

# Some timing logic

subprocess.call("display " + imagepath, shell=True)
