Add support for displaying images/stickers in the terminal

[WeetHet]

Some terminal emulators support viewing images using imgcat (or other similar tools). Would be great to see support for those here (as a configuration option).

Hi @WeetHet - thanks for suggesting a new feature. I'm a little hesitent to adding it, mainly because I personally prefer simple/plain TUI interfaces, and also because I suspect there could be some issues getting an image viewer library to play well with the ncurses framework used by nchat. One option might be to look into other clients like telega.el for emacs, not sure if it displays images inline in terminal mode though.

We still are supposed to view images somehow, and with this feature we could probably make it work without external image viewer

+1 to this feature, being able to quickly see images without opening them would be very helpful.
felix uses chafa for that, which is expected to be installed separately.

Thanks for sharing! Looks like chafa provides some sample code for getting it to work with ncurses, so I suppose it would be feasible. Might look into it, but cannot promise anything.

This was also requested in #149 (which suggested to use ueberzugpp for implementation).

I do like the nnn way with both simple shell plugins that open external programs and then return:

• preview-tui
• nuke

With many ways to open files, using features from: tmux, kitty, wezterm, etc ... to have options with GUI, TUI, TTY (viu), Framebuffer (fim, fbida). And not just xdg-open.
Or just show sticker/gif with a shell script or package and then return to nchat.

Maybe something like (proposal/feature):

Select Message > Alt-v > show reaction, open with:

1. Default viewer on desktop (X11/xdg-open|wayland), or can be custom in config.
2. Show big 32x32 ANSI/ASCII art pop up, showing emoji. Can be done with: aalib, libcaca, viu, chafa, timg, etc.

Similar with an Image
