As an editor, I want to be able to add a photo to a lightbox and see what (if any) lightboxes it is already in from the "Edit Image Details" page so that photos can be put in lightboxes more easily. Currently, the "Edit Image Details" pages give no indication whether the image is part of any lightboxes, and there is no way to add a photo to the lightbox from that page. So it is a multi-step/page process to determine if the photo is already in the lightbox and add it if not. This should all be able to be completed from the image details page.
