There seems to be a bug with this slideshow plugin that doesn’t allow the workflow event of when this slideshow is clicked to actually be triggered.

I just submitted a bug report #11841

In the meantime you can follow my previous instructions. Put the datasource to be the slideshows current slide so that the image that is currently displayed in your slideshow is displayed in the popup image.

To open the popup you should put a group that is transparent to overlay the slideshow element, but not completely as you don’t want to take away the navigation (hopefully bubble would fix the plugin to allow the workflow event ‘slideshow is clicked’ so you don’t need to use the ‘workaround’ of a group overlay to trigger the popup to be displayed).
