You can have that functionality integrated within tmux with https://github.com/csdvrx/sixel-tmux/ : if you terminal doesn't support sixels, you'll at least see something close to the picture they represent.

Then of course it's not pixel-perfect unless you make your terminal very large (like 800x240 instead of 80x24) but something being better than nothing, I'd argue it's for the better if all you can do is 80x24 with no pictures otherwise.
