SendImage() — Sends an image file
Synopsis
SendImage(filename)Sends an image on a channel, if image transport is supported. If
the channel does not support image transport, and there exists a
priority n+101 (where n is the current priority), execution will
continue at that step. Otherwise, execution will continue at the next
priority level.
Returns 0 if the image was
sent correctly or if the channel does not support image transport;
otherwise, returns -1.
