Flickr is a photo management site where members can store, search, sort and share photos. You can group your photo and groups have different kind of privacy levels. Groups can be public or completely private or some member can see them. You can also give different permission levels to use your photos. Flickr gives also opportunity to great some stuff out of your photos or the photo you have permission to use. Stuff means like cards, photo books, calendar or stamps. You can also explore photos by place. Map shows where you took those photos or you can browse a world map to see where other members have been. Other members can comment photos or you can add some comments directly on your photos.
