Can Image Preview be tweaked by user?

[dedguy21]

I'm not sure which program(s) are being used for image preview, but in wezterm kitty & foot terminals in wayland environment, it comes out very pixelated and is basically unrecognizable and useless. I was wondering if the user had an opportunity to modify the previewer script some how. I use 'lf' and 'vifm', and my preview scripts works across the three terminals, would like to leverage it for 'walk'

Preview is implemented inside walk.

My first thought was to use the icat protocol as well. That would be a nice-to-have
