Flickr is an excellent tool that explores the idea of photo management and sharing. Flickr is ideal for people who have family and friends that they want to share their photos with as it is free and gives you the option to share with the everyone or simply a small group of people you choose. A really important feature offered by Flickr is know as Creative Commons. Creative Commons explores the idea of copyright and provides alternatives for the person who is sharing their photo/image. The Creative Commons feature consists of four alternate categories in which the photos are able to be used for. These four features include:
Attribution: You let others copy, distribute, display, and perform your copyrighted work - and derivative works based upon it - but only if they give you credit.
Noncommercial : You let others copy, distribute, display, and perform your work - and derivative works based upon it - but for noncommercial purposes only.
No Derivative Works: You let others copy, distribute, display, and perform only verbatim copies of your work, not derivative works based upon it.
Share Alike:You allow others to distribute derivative works only under a license identical to the license that governs your work.
This above definitions have come from the flickr website
Here is a link to a photo I have found of a dragonfly using Creative Commons:
Flickr can be linked to Keirsley and Schneiderman's Engagement Theory, as students will undoubtedly be engaged in the task due to the fact that they are in charge of their learning and the photos in whihc they choose to use for the particular set task.
