The Panorama presentation utilizes Paver JS, allowing ultra-wide images to be panned horizontally using mouse or touch gestures.

For best results, under Image Renditions ⇒ Photos, set Width to its maximum value, then use the Height slider to manage the size of your exported images. Because of high-resolution displays, such as Apple's “Retina” displays, you should choose a rendition height 2x your desired display height. For example, if setting Presentation Height as 480px, export your photos with a height of 960px.
Thumbnails are only used to represent the album in the parent Album Set; choose your thumbnail sizes accordingly.
