Make it work like Smartpocket - Piwigo/piwigo-bootstrap-darkroom GitHub Wiki

You can configure the theme to function like Smartpocket. This means:

• Masonry style thumbnail page with Ajax loading
• Tap on thumbnail opens the fullscreen slideshow (as opposed to the default setting which opens the picture details page)

To get this behaviour:

• Install and enable GThumb+ or gdThumb plugin
• Install and enable RV Thumbnail Scroller plugin
• Go to Administration -> Themes -> Bootstrap Darkroom configuration -> Appearance tab
• Set Thumbnail link target to either PhotoSwipe (for both desktop and mobile), or PhotoSwipe (mobile devices only)
