Scaling pictures

[Kajsa Anka]

I would like some advice, I'm going to build a small app that will, among 
other things, scale images so that they can be published on a web site. I've 
never done any image processing in python before so I would like to ask what 
is the best way of doing this, I will not do anything else than scaling the 
images.

I found the Python Imaging Library but before I dive into that I would like 
to know if there is a better way of doing this.
