Beautiful gallery display, like all of their others. My only problem is that you have to edit the XML file by hand every time you upload a new file. That, or use their site to reassign the images and captions. Either way, it's not useful for a CMS site, where, the point is to make sure the client doesn't ever have to see the code.
Maybe the paid version has that capability? It would certainly be nice.
But like I said, it's beautiful. And if you don't mind the slight tediousness, there's nothing wrong with it.
