Is there a way to have an "add to lightbox" feature (not to be confused with the lightbox effect of enlarging an image on screen) for a photo site. Here is one example from another site that has it. If you hover over a thumbnail image you see a little lightbulb and if clicked on it will add the image to a "lightbox"... this is sort of like a "save to wish list" in a store site.

I want the user to then be able to go to their lightbox and have the option to either print a pdf of the images or send them via email.
