Displaying your photos in a lightbox when a user clicks on a photo in your widget is a great way of keeping your visitors on your website while still giving them the ability to see a larger version of the photo with the caption.
Do to this, set the Photo Link option to Lightbox under the Advanced Settings tab for your widget. Your photos will now open in a beautiful lightbox when clicked.
Of course, it still looks great on mobile as well.
The lightbox option is available for all Pro widgets.
