Flickr

Flickr is an online photo and video hosting platform used by photographers, hobbyists, and visual artists to store, organize, and share their work. The service allows users to upload images in high resolution, organize them into albums and galleries, and tag content for searchability. It supports both free and paid subscription tiers, with paid plans offering expanded storage limits and ad-free browsing. Flickr also functions as a community space, enabling users to follow other photographers, join interest-based groups, comment on photos, and participate in photography discussions. Many creators use it to license their images through Creative Commons or explore stock photography opportunities, and it is frequently referenced by developers and researchers for its large, tagged image datasets.
