What is Flickr?

Flickr is a photo sharing and hosting service that supports a community of people that can share and explore each other’s photos.

Users can share and host hundreds of pictures for free on the site that was created by Ludicorp in 2004 and acquired by Yahoo in 2005.

The service is widely used by photo researchers and bloggers to host images that they embed in blogs and social media.
