save to lightbox like "shutterstock"

Hi,
someone of you know a plugin that can let you do something like here http://www.shutterstock.com/cat.mhtml?searchterm=birds&search_group=&lang=en&search_source=search_form#id=116352187
I have a gallery of photos, I’d like to have a button “save to a lightbox”. When you click on it you are able to create your own gallery of images that you like especially.

If someone can help me it would be very appreciated.
thank you in advance.
