Simple script to make .png thumbnails from .zip archive...

Thanks a lot.
I'm really new to python, and haven't coded in over a decade, so
please be patient. :-)
I'm able to read a .jpg from a .zip archive, but can't seem to
manipulate it. If I do this:
zip=zipfile.ZipFile(inURL,mode="r")
picture=zip.read("00.jpg")
I get the image, but it is of "type" ZipFile. How can I change it to
type Image? Or am I thinking about this in the wrong way? I would
like to follow this with something like:
picture.thumbnail((128, 128), Image.ANTIALIAS)
But obviously I can't do this directly. What am I missing?
