Lightbox is a special type of collection that provides easy access to assets. You can quickly access Lightbox to add or delete assets.
Each user has an exclusive Lightbox that is automatically created when the user logs in to Adobe Experience Manager (AEM) Assets Brand Portal.
Although Lightbox resembles a collection, you can't perform all the actions that you can normally perform on collections. For example, you can't delete, share, or view settings for a Lightbox. In addition, you can't add it to other collections. However, you can edit the assets inside a lightbox.
