Multiple Lightboxes one on top of the other


I am in need of a lightbox script that enables me to call another lightbox from within an opened lightbox, then be able to close the second one and keep the first one open, in other words they need to be independent (although the 2nd one doesn’t need to remain open on its own).

I hope that makes sense!?

I imagine it will involve some customization of a plugin but I have no idea where to start, of course it would be great if one already exists that allows this but none of them say so and I don’t want to start trying every single plugin.

I have already tried fancybox but when I open the 2nd window it just closes the first.

Any help really appreciated.
