How about forget PIL's show and its automagic behavior.
Use PIL's image save to write the image to a nice, known location, such 
as C:/temp/pic.jgp -- nothing but alphanumerics + ':/.'
Next test how to run a known external viewer from a command window.
Then use os.system or subprocess to run it with the same command line.
Package the two lines as a myshow(params) function.
