doesn't work with tmux on MacOS

[thomasd3]

when invoked from a tmux window, the display seems to show a base64 version of the image file

Hi! Could you please list the versions of tmux and iTerm 2 you're using? Also, are you using regular tmux or tmux integration mode?

[thomasd3]

I'm using iTerm2 version 3.3.9 and tmux 3.0a

I'm not using the integration mode because I didn't know what it was until I read your question :) now I will look into it! thanks!

Hi. I am having this issue to. I am using regular tmux in iTerm, but also have tried in Alacritty with tmux and still no images. This is tested using ranger, which works in a regular iTerm session, but not in tmux. Therefore, seems to be a problem between tmux and imgcat.

@atanasj I'm seeing the same thing. imgcat works for me in an iTerm2 terminal, but not in a Tmux window.

Note to self: this is a way of working with tmux:

@eddieantonio, that looks promising… How best to get this running inside tmux on alacritty I wonder…
