Progress made in case it helps anyone else
[attached orderby=title]
<a href='[field url]' rel='wp-video-lightbox'>
[field thumbnail]
</a>
[/attached]
This was done using the wp-video lightbox plugin
What I would like to know, is it possible to make the lightbox create a gallery slideshow?
Currently used the following code, which worked nicely to create agreed of attached images
[attached orderby=title]
[field thumbnail]
[/attached]
But would like the thumbnail to be clickable to a full size image, in a lightbox pop out
