Yes, we can do this with the Python Imaging Library (PIL):
PIL is well suited for image manipulations. If we use PIL, the problem is
not bad at all --- I think it would involve doing something like:
## Warning, warning, untested code
for file in files:
im = Image.open(file)
print "%s has dimensions %s and is of size %s bytes" % \
(file, im.size, os.path.getsize(file))

I think this should be a great first Python script. *grin* By the way, if
you'd like more details on os.path, you can look at:
Another interesting module would be the 'glob' module:
which helps us pull all the files in a given directory.
Hope this helps!
