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

Ha! No, my question was clumsy.
If I know the name of the viewer that I want to use (say for example: 
‘ImageMagick’), where do I find the argument that should be used in a 
line of code such as this:
ImageShow.register(MyViewer("gwenview"), -1)
I want to replace ‘gwenview’ with the name of my favourite viewer (for 
example: ‘ImageMagick’).
