Allow images in popups (sixel protocol?)

[eugenesvk]

I'd like to have a keybind that shows an image in a popup window, for example, a keymap cheat sheet on F1
As far as I'm aware, many terminals support a special standard imaging protocol https://www.arewesixelyet.com/ for that allows you to display images in the terminal

Would be great if I could control that behavior via a Helix command

I dont think we want to support feature like that from inside helix. There are multiple different nom-stanrd protocols. None of which are stadarized and usually only support by an emulator or two. Thisncoukd be done by plugins in the future but I dont see any reason why this needs to be integrated into core.

In the meantime.you can simply open images in a seperate window, with a terminal multiplexer or the terminal emulator (all of these usually support both overlaysnand splits)

Sixel is supported by a dozen terminals according to https://www.arewesixelyet.com/

+1 Adding image preview/ rendering would be particularly useful for markdown notes. I have lots of notes containing images and this would be perfect to avoid using GUI editors/ note apps.

+1 both for notetaking systems and for math formula preview in typesetting

Hm... I could rather see this as a plugin at most.
For me, helix is a terminal editor which should work fully within a terminal
but a terminal doesn't require displaying images like in the tty so I don't see this feature to be in core.
