What would be the best plugin for a photo gallery that opens other galleries?

Hi there,

I'm looking to add a simple photo album plugin to my site that that will allow me to use the homepage photo gallery area (beneath the video area) to show photos that when clicked will open a full album in a lightbox. I don't want merely to be able to review all of the photos on the page, but I want the photos on the page to be the "album covers" of full photo albums that are not on the page.

There's a dizzying array of plugins at different levels of cost and functionality. I don't know where to go to achieve what I want without complicating things or overspending.

Thanks!

Ozzie
