I think I also kept track of a weight for each image to account for 
that, but it's a good point that I should have mentioned.

A dedicated tool wouldn't need to load all images into RAM before starting.

I should have thought of this; I have written code in Python for 
handling PPMs. Only problem is that I have to make and format a list of 
the files so that Python can read the list. My Python skills are not 
such that I can call a Python program with program(args). Still, a Vim 
script should make quick work of that.

Shouldn't need longs. Hope not, at least, I've got no idea how to deal 
with them in Python.

import os
import sys
path=sys.argv[1]
filelist=os.listdir(path)
#print the file list:
print "\n".join(filelist)
for filename in filelist:
  if os.path.isfile(filename):
    #do whatever

and start your script with the folder as a parameter, e.g. ./foo.py
/home/usr/blah
