Thanks for the reply! Much appreciated.
How I envisioned it working was as something extremely simple for my clients to use.
It would work just the same as adding an image to a page (just like you would currently in Power CMS Builder). You would click the add lightbox gallery and a wizard would walk you through adding your images. It would have to be so simple as my clients are so non-technical.
There are tons of WordPress Lightbox plugins out there as examples. Maybe you guys should start thinking about a plugin approach to Power CMS? This is something I would gladly pay extra for.
