Flickr
Flickr is the most popular online photo management and sharing application on the web. Flickr offers users a number of useful features. You can securely share photos and videos (up to 90 seconds) online and privately show content to friends and family. Users have the option to make their pictures private or public, however around 80% of the pictures on Flickr are public. No fee is required to start loading and sharing pictures. Other features include maps to track where and when photos were taken, tagging and commenting on pictures, and the ability to create postcards and other products. It’s also possible to include your photo album into your blog….
