Lightbox / Slideshow

Hey,

I have a grid of images which open up an article in a lightbox using '[lightbox] Content in a lightbox' when clicked.
I want to be able to have slideshows and flash in these lightbox articles too.
I've added a slideshow to the article but the slideshow doesn't work.
I can see in firebug that the images are supposed to be changing, but this doesn't reflect in the lightbox.

Only first image is currently setup

Thanks

James
