huh, what if the image encoding is 8 bits per R, G, B values of the pixel, then one can encode the same amount of text in less pixel dimensions (3 letters would need 1 pixel instead of three 12x12 pixels)

The top line can be the OCR-able instruction on how to decode the rest of the image, and the rest of the image would be random-looking colourful palette. It might not even need to use 8 bits per character, since ANSI is 7 bits/character.

then it's no longer an image, as the one in the github repo, you would be encoding the text as characters and sending it as an image.

You can achieve this by changing the extension of an image file from .bmp to .txt

Guys, not to be mean, but maybe chill with the state of the art research and go back to studying fundamentals.
