API Feeds
In the previous examples, the feed FlashVar is still pointing to the default Flickr feed. This URL starts with the api:// scheme, which is a custom protocol that the embeddable wall recognizes, telling it to load from an API. The wall can display images from the Flickr or Picasa APIs, by user, search, album, etc.
Set the feed FlashVar to an api:// URL like one of the examples below, and you'll see the specified images in your wall.
Flickr
api://www.flickr.com/?user=surrealize
api://www.flickr.com/?search=puppy
api://www.flickr.com/?album=72157594567688537
api://www.flickr.com/?group=645450@N20
To find an album number, open a Flickr set in your browser. The album number can be copied from the last part of the URL, e.g.: http://www.flickr.com/photos/thomashawk/sets/72157594567688537/
To find a group ID, open a Flickr group and then click the RSS feed button in your browser's address bar. The group ID can be copied from the URL, e.g.: http://api.flickr.com/services/feeds/groups_discuss.gne?id=645450@N20&lang=en-us&format=rss_200
Picasa
api://picasaweb.google.com/?user=corcrs
api://picasaweb.google.com/?search=puppy
api://picasaweb.google.com/?user=jajonet&album=BLIJDORPThe user and album parameters can be found in your Picasa album's URL, e.g.: the last example above corresponds to this URL: http://picasaweb.google.com/jajonet/BLIJDORP/
Note that...
URLs with & characters, like the last example, need to be encoded. The last example would need to be set as:api%3A%2F%2Fpicasaweb.google.com%2F%3Fuser%3Djajonet%26album%3DBLIJDORP
