I have crafted a program to convert farbfeld images to sixels: https://github.com/ilabdsf/ff2sixel
I am going to use it myself to quickly display images over SSH. Hope someone else finds it useful. Too bad st does not have a patch to display sixels, so I am going to use mlterm when I need to browse images. One simple way to implement it in st is to cut out sixel images, convert them back to farbfeld (with separate process) and pass result to lel. Not going to do it now, just an idea. Any feedback is appreciated.
