Lightbox pops up behind FooBox in foogallery

I’ve designed a website for a client and they wanted to display a slideshow once the image is clicked on, I’ve done this using FooBox (as the gallery I’m using is FooGallery) but when clicked on the original Lightbox of the image (which doesn’t have any ‘next’ buttons) comes up behind and stays there. Haven’t been able to figure out how to get rid of it.
