Best Lightbox Gallery integration?

Hey Everyone. I’m currently building a website for a Home Stager (Think of them like interior designers). I have her gallery set up, I just am looking for a way to implement a lightbox like gallery for people to go through. I bought RoyalSlider and it doesnt seem to do a lightbox setting, despite the developer showing off that feature on the demo.

Is there a quick way to do this so that my client can just add and remove images from a gallery and not have to worry about it any further?

Here is what her website looks like, so I need each of those thumbnails to open up to a lightbox setup, much light Facebook has. Something pretty, and flashy (however, not flash) with mobile integration would be preferred. Thanks.
