Flickr is an online image hosting and sharing website where users can post photos and videos. Basic accounts are free and allow uploading a limited number of photos and videos per month. Users can create galleries and groups to share and organize images. Groups can be public, invite only, or private. When uploading images, users must abide by Flickr's terms of service which require owning the copyright for any uploaded images.
18. Flickr Account Settings Contacts You can mark anyone you meet or invite in Flickr as a contact. You can organize your contacts into friends, family, or friends and family. The different types of contacts let you choose who sees what in your photostream. When you upload photos you can choose to have them be viewable to everyone, or just people you have marked as friends and/or family .
21. Adding Images To Flickr Flickr's Terms of Service require that you own the copyright to any image you upload. That means permission to use an image is not enough. You must own the full rights to that image. It's best to stick to images you have taken.
29. Flickr Groups Groups Groups are a way to share photos among multiple users. They can either be public, public (invite only) or completely private. Every group has a pool for photos and/or video and a discussion board for talking.
