Hi,
Great work. Flicker has been providing their users with advanced RSS feed features like: "latest pictures from all albums", "album pictures", "album pictures" and even RSS feeds to all of a user's album thumbnails. However, users were faced with difficulties whenever there was a need to create a new picture gallery or update new pictures into existing galleries - while pictures could be embedded into a slideshow, any new picture galleries that were created or pictures that were updated had to be separately updated into RSS feed slideshows.
