This is not difficult to do using the Python Imaging Library.
If you are doing significant size reductions, you probably want to smooth 
the image a little first to avoid pixelization problems.

Contact me by email if you want me to send you some code I wrote to do this 
as part of a web photo gallery generation applet (see 
http://www.ics.uci.edu/~eppstein/pix/ for results). My program uses 
Mac-specific user interface code so would require significant modification 
to run on your PC, but the image resizing stuff should be pretty portable.
