Creative Commons images:
Most students (and adults) are used to going to Google images and copying a picture. It is important to know that most Google images are copyrighted and cannot be used unless permission is given by the artist.
Below are some links to very good, smart sources that give you access to copyright-free images for use in your projects.
What is Creative Commons??
A non-profit organization founded on the notion that some authors may not want to exercise all of the intellectual property rights the law affords them. Creative Commons has developed a set of free public licenses to enable authors to share their work with others.
