This is very similar to the grouping functionality for images. The only difference is that "rel" attribute should be set to
lightshow instead of "lightbox". Using the same example as above, we could launch the images in a slideshow by doing:
<a href="images/image-1.jpg" rel="lightshow[roadtrip]">image #1</a> <a href="images/image-2.jpg" rel="lightshow[roadtrip][caption 2]">image #2</a> <a href="images/image-3.jpg" rel="lightshow[roadtrip][caption 3]">image #3</a>
If you want to display a "start slideshow" link at the top of the page for example (e.g. in a views header), you could try the following:
<a href="#" onclick="Lightbox.triggerLightbox('lightshow', 'groupname');">Start slideshow</a>
