Flickr is an image and video hosting website and was one of the earliest Web 2.0 applications. In addition to being a popular Web site for users to share personal photographs, the service is widely used by bloggers as a photo repository. Its popularity has been fueled by its organization tools, which allow photos to be tagged and browsed.
I can upload pictures to Flickr to share with family and friends. I can also make a slideshow of my uploaded photos. I can use Flickr as an online storage space for photos.
