Quite a while ago I started KittyTerminalImages.jl - a package that allows one to show images generated by Julia directly in the terminal. I never registered that package as it is still very experimental and I did not find the time to work on it, but finally decided to do so in the hope that I can get more feedback for what is missing and if there are some issues in some setup.
Caveat: This only works if one uses kitty - a super fast terminal emulator for macOS os Linux (but not windows unfortunately). Also, this package does currently not work with ssh, screen or tmux but maybe it might be possible to add such functionality later.
Here are some screenshots:
