It doesn't do much. It recurses into the filesystem of the photos folder and displays a link to a gallery if it finds a folder, or a link to a photo if it finds a photo.

• Thumbnailing with cache
• Swipe-able galleries
• Keyboard arrows to navigate gallery
• HTML5 history enabled: each photo has it's own unique link for sharing without polluting your history. Browser history back is hierarchy-based
• HTML5 full screen
• Context-aware back button for full-screen operation: history back when navigating the website to avoid polluting the history, hierarchical when coming from external links.

• rename photos-sample to photos
• create folders
• create gallery.json in each folder (optional) with the following structure

     {
         "name": "gallery1",
         "description":"a test gallery",
         "flagship":"_DSC4316.jpg",
         "ignore" : ["_DSC4307.jpg"]
     }

(all fields are optional)
