Flickr is one of the oldest photo-sharing communities on the web, and it's still active. It hosts billions of photos from photographers of all levels, organized into albums, groups, and tags. The platform supports high-resolution uploads, and the community aspect — commenting, favoriting, joining groups — is what sets it apart from a simple photo dump. Many photographers use Flickr as a portfolio and a way to get feedback from other photographers.

The free tier gives you 1,000 photos with limited storage, and paid plans remove those limits. The site has been through ownership changes and redesigns over the years, but the core experience of browsing beautiful photography and connecting with other photographers remains. It's particularly good for nature, landscape, and street photography.
