Attachments with Lightbox
The Attachments with Lightbox web part displays a gallery of unsorted attachments of a specified page. After clicking an image in the gallery, it is opened in full size in a lightbox. The web part is useful when you need to display a gallery of images related to a single page, typically the currently displayed page.
Please note that you need to include jQuery in the master page or web part properties. See this web part's properties for reference.
