Image Prep (Gimp)

Resize Images to 800x480

Color dithering - Floyd-Steinberg (normal)
Save as pbm

Steps to use

Add images to an "input" folder
Run img_process.py for image prep (can skip doing this in GIMP)
Run img_generate.py (breaks image into small chunks to avoid memory allocation errors)
Upload contents of the "bmp" folder to pico
Run disp.py on pico

Features coming soon (aka in 3 months hopefully)
