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

[Paul St George]

Is there, somewhere, a list of viewers and their names (for the purposes 
of this script)?

I am assuming that if I want to ImageMagick (for example), there would 
be some shorter name - such as 'magick' - and it would be lower case .
