In case you're like me, and you wouldn't think of using a terminal without Tmux, the experimental sixel branch was finally merged[0] as of about 10 months ago. This means you can finally build mainstream Tmux with --enable-sixel and use tools like lsix in Tmux!
If you're curious if your favorite terminal or multiplexer supports sixel, you can check out the "Are We Sixel Yet"[1] site.
