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

No, this tends to become a maintenance problem. Instead write a little 
module of your own


from PIL import ImageShow

class MyViewer(ImageShow.UnixViewer):
    def __init__(self, command):
        self.command = command
    def get_command_ex(self, file, **options):
        return (self.command,) * 2

ImageShow.register(MyViewer("gwenview"), -1)


(replace "gwenview" with your favourite viewer) and import it before using 
Image.show().
