iTerm2 has a escape codes for viewing images, but I haven’t seen any other terminals picking it up: https://www.iterm2.com/documentation-images.html

This is nearly what I'm talking about but it requires the terminal emulator to understand the image format. I guess that makes sense for transfer efficiency, and if you want a pixel-level API you could just transfer BMPs.
