retrieving a photo: https://www.googleapis.com/buzz/v1/photos/{userId}/@self/{albumId}/@photos/{photoId}

With live data, it look: https://www.googleapis.com/buzz/v1/photos/farago/@self/5251364904403459921/@photos/5251366163678993586?alt=json&prettyprint=true

"The read-only endpoints will return public data without authentication. For authenticated access to photos endpoints, you must be granted an OAuth token for the user with both Buzz and Photos API scopes. For existing users, you'll need to discard OAuth tokens scoped to Buzz API and request authorization to both scopes," explains Google.
