Virtual Tourist is an app that allows users to view Flickr images from around the world simply by dropping a pin at their desired location. Once viewing photos associated with a particular location, users are able reload the album with more images from the area, while retaining any existing photos they may have liked. The app is highly efficient with the way it loads images into each cell, only starting a request if one is not currently being made. This allows for a more fluid user experience.
