Using the script below as a baseline, can you guide me on how to expand the script as follows:

1) Allow the user to enter a path to a directory containing jpeg files.

2) Using that path, process all the .jpg files contained in that folder(use the testimages.zip set of images)

3) Extract the GPS Coordinates for each jpg (if they exist)
