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

It becomes a maintenance problem.

Alternatively you could:

Just write your own show function which accepts an Image and displays it with 
your program of choice. You might need to write some equivalent code which 
saves the Image to a file first, and removes it afterwards.

You could copy the show() code into a function of your own (i.e. in your own 
codebase) modify that to suit, then monkeypatch the class:

  Image.show = your_personal_show_function

when your programme starts. That way the code changes are not in the PIL code.
