Display of JPEG images from Python

[David]

I would like to display a JPEG image from Python on a Windows machine. 
I Googled 'python jpeg display' and have not found what I am looking 
for, which is code I can call directly and pass the image.  I see the 
PIL library lets me do all sorts of image manipulation, but is there a 
convenient way to display results?  I guess I could issue shell commands 
to a graphics display package such as IrfanView, but I thought there 
might be a cleaner method.
