True, but I wanted to have some control over the image window,
fullscreen, colour depth, etc. I am also exploring pygame. I will try
your suggestion as it is so much simpler.
Being a novice, I had been frightened off using shell=True. See
<https://docs.python.org/2/library/subprocess.html#frequently-used-arguments>.
Is this equivalent?
p = subprocess.Popen('display', + imagepath)
so
p = subprocess.Popen('display', 'test.png')

You are very right. The show() method is intended for debugging purposes and
is useful for that, but what method should I be using and is PIL the best
imaging library for my purposes? I do not want to manipulate images, I only
want to show images (full screen) on an external display. I want to use
Python to control the timing of the images.
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)
