According to this:

http://www.pythonware.com/library/pil/handbook/format-jpeg.htm\

"""
PIL reads JPEG, JFIF, and Adobe JPEG files containing "L", "RGB", or 
"CMYK" data. It writes standard and progressive JFIF files.

Using the draft method, you can speed things up by converting "RGB" 
images to "L", and resize images to 1/2, 1/4 or 1/8 of their original 
size while loading them. The draft method also configures the JPEG 
decoder to trade some quality for speed.
"""

So it looks like PIL can produced reduced quality images from jpegs on 
the fly. give it try -- you'll save memory, if not time, and I think 
you'll save time too.
