 MR> okay i used windows paint and saved as monocrome.

He added support for sixel around the same time. I don't remember the limitations of the format, but you get colours and decent looking images. Should be possible to find conversion utilities online.

I think there's a demo of it on my BBS immediately upon connection if you're using a high enough SyncTERM version. (An image will show up before the login menu appears.)

The display function I'm using is like this, where 'fn' is a string, path to a sixel file:

load('cterm_lib.js');

function show_sixel(fn) {
 if (console.cterm_version >= 1189) {
  var image = new File(fn);
  if (image.exists) {
   if (image.open("rb", true)) {
    var readlen = console.output_buffer_level + console.output_buffer_space;
    readlen /= 2;
    console.clear();
    while (!image.eof) {
     var imagedata=image.read(readlen);
     while (console.output_buffer_space < imagedata.length) {
      mswait(1);
     }
     console.write(imagedata);
    }
    image.close();
    return true;
   }
  }
 }
 return false;
}
