The Pro option features "unlimited" storage, advanced statistics, advertising-free browsing, videos up to 10 minutes in length, "premier" customer service, and promotional offers with other partners. In May 2011, Flickr added an option to easily reverse an account termination, motivated by the accidental deletion of a Flickr user's account, and public reporting of its protracted restoration. Flickr may delete accounts without giving any reason or warning to the account's owner. As a result of the SmugMug buyout, Flickr added the ability for users to download all of their account data, such as photo albums, contacts, and comments. Organization The images a photographer uploads to Flickr go into their sequential "photostream", the basis of a Flickr account. All photostreams can be displayed as a justified view, a slide show, a "detail" view or a datestamped archive. Clicking on a photostream image opens it in the interactive "photopage" alongside data, comments and facilities for embedding images on external sites. Users may label their uploaded images with titles and descriptions, and images may be tagged, either by the uploader or by other users, if the uploader permits it. These text components enable computer searching of Flickr. Flickr was an early website to implement tag clouds, which were used until 2013, providing access to images tagged with the most popular keywords. Tagging was further revised in the photopage redesign of March 2014. Flickr has been cited as a prime example of effective use of folksonomy. Users can organize their Flickr photos into "albums" (formerly "sets") which are more flexible than the traditional folder-based method of organizing files, as one photo can belong to one album, many albums, or none at all. Flickr provides code to embed albums into blogs, websites and forums. Flickr albums represent a form of categorical metadata rather than a physical hierarchy. Geotagging can be applied to photos in albums, and any albums with geotagging can be related to a map using imapflickr. The resulting map can be embedded in a website. Flickr albums may be organized into "collections", which can themselves be further organized into higher-order collections. Organizr is a Web application for organizing photos within a Flickr account that can be accessed through the Flickr interface. It allows users to modify tags, descriptions and set groupings, and to place photos on a world map (a feature provided in conjunction with Yahoo! Maps). It uses Ajax to emulate the look,
