and w3m has w3m-img if you want to get just one step more graphical while still being fundamentally a tui (it does terminal/character cell layout, then uses the WINDOWID to stuff images on the terminal screen. Probably the kind of thing wayland doesn't allow? :-)

(hmm, the neonmodem FAQ mentions it has an image rendering feature too, to come full circle)

w3m also supports image display through the sixel, kitty, and mlterm image protocols; these should also work on wayland with terminal emulators that support them (i.e. almost any terminal except vte or alacritty).
