I have a clickable thumbnail on the page. Click it and Lightbox opens. I want the slideshow in Lightbox to start to play automatically. I have added the behavior "Control DMXzone Lightbox" to the clickable thumbnail on the page and selected "act in Current Window" and "Action Start Skideshow", but the slideshow does not start. Are there additional parameters I must set in the code once I have added the behaviour? This is what I get so far using the above mentioned standard procedure: onClick="controlDMXzoneLightbox('startSlideshow', [], window)" . This is Lightbox 1.0.15 and all the Libraries are up to date / latest Versions. It is not working both locally and online after Publishing.
