Where can I find the Featured Slideshow? As opposed to the Album/Recent Photos Slideshow (for more visit here), the Featured Slideshow must be enabled/embedded by the photographer. You can find it either on the user's homepage (▼) or on a third party websites.

Setting up the Featured Slideshow. Featured Slideshow is one of the built-in pages available from the "Layout" roll-down menu on your homepage. Once you enable it, you can set its properties.

Customizing the Slideshow. While viewing the Featured Slideshow on your Homepage, there - in its upper right corner - is the Tools panel.

In the Slideshow Tools panel, there you can set its site, speed and most importantly which photos to display (the default settings is "All Recent Public Photos").
