Guacamole does send images, yes, but there is also an OSC which temporarily redirects output to a pipe stream: https://github.com/apache/guacamole-server/blob/99e6f89eba56b6effc189d1c2c160686ed880beb/src/terminal/terminal_handlers.c#L1314-L1320 There is an example of this within guacctl: https://github.com/apache/guacamole-server/blob/99e6f89eba56b6effc189d1c2c160686ed880beb/bin/guacctl#L285-L301 - Mike
