Add-on:XZen

A simple but effective Zenfolio browser for XBMC. Supports user galleries (with single password protection), and you can also browse by category, or look at recent and popular photos.

Two important notes: in XZen to access your user galleries you must login with your Zenfolio username NOT your email (even though you can generally login with both the API uses username only). Also - your Zenfolio galleries/groups must have cover thumbnails to show up in XZen.

Zenfolio is a gallery site aimed at professional photographers, so the quality of galleries is often a bit higher than your basic flickr type galleries.
