this one is awesome.

i like the option to be able to put a group of images inside of the lightbox frame.
like a gallery within a gallery, so you know what image is next, and you can also skip images and not have to click thru all to get to just the last one

this is pretty neat too. same style, just less options and a pretty neat placement idea rather than just always auto center with a grad overlay bg
