This shows how to load images from a zipfile. The script itself
will take the name of a zip file and display all the image inside
the zip.

You will want to change to code yourself to suit your game,
but this script shows you how to find images inside a zip file
and then load a specific image from the zip.

This example originally was included as an example with earlier
versions of pygame.
