You're really going to need to tell us more about your goals. What kind 
of images? where do they come from? what formats?

Some image formats types are designed to provide lower res info first in 
the file, then fill it in with more detail -- I think it's called 
"interleaving".

Also, with jpeg, you can get just the "DC" signal, which is essentially 
the average of each 8x8 block of pixels (I think), which can be used as 
a low-res version -- but I don't' know if you need to read the whole 
file anyway to get it, or whether libjpeg, or PIL or ??? supports that.

Unless you are getting your images from a net connection that may be 
slow, I don't think there is much point to this anyway.
