This is a great idea. I always wanted KDE konsole to e. g. show images inlined as is. This is possible via magick six:-, but I wanted this to be natively. I want the terminal to be able to work with any data and display it in any way. No need to simulate the 1980s era anymore (except for backwards/legacy support). So great idea here really.

Kitty and several other terminal emulators, have built in graphics display already. IIRC, this is called the kitty protocol, but I might be mistaken.

I did that with Sixels, no Rust needed, no 3D crap, no ad-hoc addons, just old vt340 support in XTerm.

That's how I read images under a remote pubnix with tut using a Mastodon account over plain SSH.

Chafa and XTerm. It works.
