    Apparently there are escape sequences for it; see my response to the parent post.

    Even if there weren’t, if a given terminal supported either the older Sixel or the newer KiTTY graphics protocol, it can outright display arbitrary images.

    Mainline tmux doesn’t support either protocol, though there’s a fork that does do Sixel. They’re using tmux, so I assume that that’s not the route used.
