They just merged sixel support (the oldest images in terminals protocol).

Which shows that they are going places gnu screen and tmux have never wanted to.

In zellij you can scroll through and flip between different terminals that show sixel images, it's quite neat, knowing that such leaps are being made.

Meanwhile as a longtime GNU Screen user, I've been using workarounds to pass through hyperlink markup (ls --hyperlink) and thinking about what I could do if there was sixel or other image protocol support - Zellij already supports hyperlinks just fine, and now images so it is very promising.
