OK I found the solution! =:-0
I was just going over the buttons page on your demo site when I saw the button linking in lightbox.
[button link="http://vimeo.com/12613824" linking="lightbox"]Open in a lightbox[/button]
Using the code I placed it in on an image like this.
[frame type="paper-stack" link="http://bluemoonstudio.org/wordpress/wp-content/uploads/2012/04/lg-img-ad1.jpg" linking="lightbox"]IMAGE HERE[/frame]
I got the link by clicking on the image and selecting the image edit button. Under the Advanced tab in the source field is the image link that is copied and pasted into the url for the page code.
And it worked the image opened in light box. I was confused because on your demo page for images-frames, the open in a lightbox example did not work (still does not) and that sort of threw me off.
But anyway that is the solution. If you have other solutions please let me know.
Thanks for your patience. ;-)
