The image hosting serving died... dug up a couple of the pictures that are missing from the OP.

Instead of going through EDuke32, you could probably write a rather simple Python script to perform a proper conversion and export process.

Very good point, found this on stack exchange.

I'm using python 3.6.4 and Pillow 5.0.0. Gizmo's code snippet didn't work for me. After little work I created a fixed snippet:

import Image
picture = Image.open("/path/to/my/picture.jpg")

# Get the size of the image
width, height = picture.size

# Process every pixel
for x in range(width):
   for y in range(height):
       current_color = picture.getpixel( (x,y) )
       ####################################################################
       # Do your logic here and create a new (R,G,:) tuple called new_color
       ####################################################################
       picture.putpixel( (x,y), new_color)

What if anything is preventing the highpal stuff from polymer working with polymost?
