I feel like a lot of these are beyond the scope of the terminal. Like, we don't need a way to cat images — we have `xdg-open`, which will open an image file in the system's default image-viewing application. It'll open any file in its default application. Integrating images into the terminal requires doing away with the text-only abstraction, and in exchange for what? Something `xdg-open` gets for us already?
