The feature you are looking for is the lightbox. You can create one using the Lightbox Lightboxes button under My Account. After the lightbox is created, a new dropdown will appear on your search pages which allows you to add the images to one of the lightboxes created. An add to lightbox button is available on all search pages as well as media detail pages. You can email a lightbox to a friend (no account on our site is required) or share it with other users (they need to be registered in order to see/edit the content of the lightbox). You also have a Buy/Download option which you can use to calculate download cost and download all the images saved at once.
