(main/image.h/image.cpp)
Slightly modified mainpulled PGM sample files from here: https://userpages.cpp to accomodate larger umbc.edu/~rostamia/2003-09-math625/images.html
Had to expand a PGM image (to file sizes being 512x512, about 1~MB size) to return any meaningful result (Using a regular sized PGM image of 11KB yielded no meaningful results)262 KB each file
Rotated and negated the image.

[Enlarged image by max permitted by program (5) to get more viewable results]
