Hi,
I don't know zipfile by heart, but python official documentation is
always good ( docs.python.org ). You need a loop in the file list like
this:
for file in zip:
process(file)
Unfortunatelly, there are too many ways to create a thumbnail from an
image. I'll cite one, using the "python image" external module, that
I've found to be very easy:
import Image
def process(file):
try:
image = Image.open(file)
image.thumbnail ((128,128), Image.ANTIALIAS)
image.save (file + '.thumb.png')
except:
print 'Skipping file', file

Module
