I am trying to convert images on my SD card so that they are viewable and printable on my Polaroid Z2300. I found a Python script here: https://github.com/nmcveity/z2300 that will convert my images, but I don't understand what a "shell session" is and how to copy/paste this script inside of a file on my SD card.

Thanks for any help! I don't have any experience with Python.
