Thanks. Unfortunately, the fellow that can answer my question left early
yesterday, so I won't know exactly the file's structure until Monday.

as long as it's a small file -- it can be much easier to help
There is one puzzling format difficulty I have with the file that
requires some attention. I hope to have that cleared up in the next
hour or two. Actually, there's a twist in the format that should be
mentioned. The first image (frame) is 640x480, and I'm pretty sure
one byte per pixel. However, every other image (frame) after that is
128 pixels square. An auxiliary text file provides where, x and y
pixel position, the small image should be pasted to form a complete
image with the 640x480 frame.
Maybe it's because I"m more familiar with numpy than PIL, but this is
how I'd do that (untested, of course...):
import numpy as np
infile = file('filename')
img = np.fromfile(infile, count=640*480, dtype=np.uint8)
for i in range(num_images):
do_something
small_image = np.fromfile(infile, count=128*128, dtype=np.uint8)
img[x:x+128, y:y+128] = small_image
....
NOTE: np.histogram2d might do what you want for the histogram
I'm sure you can do somethign similar directly with PIL.
