I am running this code so I can do some image manipulation with them.
The thing is, I have a lot of pictures to go through, so I can't type the
file names
one by one in the code. However, the order of the files to be processed
matter, so getting them in a random fashion is alright!

How do I make the python code open picture files? thanks!

## need to open random png. Any png.

from PIL import Image

## need to load picture so I can process them. Any pictures is fine as
## I need to process every picture in the folder
im = Image.open('1.png')

## do my things...
