Here are two very short videos to help you understand how the new lightbox system works. We have a few more tweaks to make to the feature but the first video shows you how you should be
creating a new image lightbox and then second video shows you how you can add an image to a photo lightbox.
We will be releasing shortly the ability to delete lightboxes, set them to public vs private and also the ability to easily send them via the site instead of copying and pasting the URL into an email to someone. Hope these help and please pass along your feedback regarding the lightbox functionality.
