Flickr - image sharing
Flickr is an image hosting and video hosting website. In addition to being a popular website for users to share and embed personal photographs, and effectively an online community, the service is widely used by photo researchers and by bloggers to host images that they embed in blogs and social media.
Photos and videos can be accessed from Flickr without the need to register an account but an account must be made in order 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.
