Use this widget to show photo sets from Flickr.

To show an entire set of pictures, browse to the Sets page for the account where they have been created and choose the Set you want to add to the application. Scroll down to the bottom of the page and click on the "Feed" link next to the icon. Copy the link for this page and paste it into the Feed URL on the management page.

You can repeat this for multiple sets.

You can show anything that has a "feed" link at the bottom of the page. Many pages on Flickr such as your account page, searches, and tags have feeds.
