Given the terminals you listed above, I assume you are referring to something very specific when you say "show images properly". However, there is a lot more flexibility to use the terminal of your choice (not to mention compatibility with other programs like tmux) if you don't need pixel-perfect reproduction.

For example, I made an image browser for the terminal [0] based on Terminal Image Viewer [1] (for most image formats) and catimg [2] (for animated GIFs) that doesn't require installing a new terminal. It works great with tmux and SSH and I use it all the time for this purpose (though I didn't initially expect to find it so useful).

YMMV, but I have found that the image quality provided by TIV for example is more than sufficient for the kinds of use cases I tend to have when in a console session and needing to quickly view one or more images. Mostly that involves quickly identifying a particular image file among others in a directory, but it's so much easier to not have to leave the terminal and change contexts that it's often more convenient to reach for it for more general tasks too. Any tradeoff in quality is more than made up for in my view by the convenience of being able to use my regular terminal.

There is also dnkl/foot, a very nice wayland native terminal with sixel support.

Thanks for the tip

Googles hterm also supports the iTerm2 protocol. Can be good for embedding a terminal in a slideshow presentation.

If your language has a REPL with appropriate control over the display of objects you can get a pretty great experience. I used it to get familiar with Haskell's diagrams and JuicyPixel libraries and it was great[0].

Yes, I'm looking for something that can display plots like a jupyter notebook could so the low resolution solutions don't really cut it. Maybe it's good as a fallback, though..

This is using the iTerm2 protocol from the REPL. So it's high resolution. For example all the plots in this Haskell tutorial [0] can be plotted in your terminal from the REPL while you are developing and the appear as they do in the PDF.

You can get 2x3 Teletext mosaics on VTE without font support. Sixel support is problematic for full-screen. You can try Tektronix graphics.

Not a terminal, but might be of interest: https://github.com/dankamongmen/notcurses

Much appreciated. Thanks!
