FLICKR

Flickr is an image hosting and video hosting website, web services suite, and online community created by Ludicorp in 2004 and later acquired by Yahoo! in 2005. In addition to being a popular website for users to share and embed personal photographs, the service is widely used by bloggers to host images that they embed in blogs and social media. Yahoo has reported that Flickr has a total of 51 million registered member and 80 million unique visitors. In August 2011, it reported that it was hosting more than 6 billion images and this number continues to grow steadily according to reporting sources. Photos and videos can be accessed from Flickr without the need of registering an account but an account must be made in order for the user to upload content onto the website. Registering an account also allows users to create a profile page containing photos and videos that the user has uploaded and also grants the ability to add another Flickr user as a contact. For mobile users, Flickr has an official app for iPhone, for Windows Phone 7, and for Android.
