This picture says it’s licensed via Creative Commons. What’s that?
Creative Commons is an organization with which authors and artists can list their work, making it available for a variety of other uses that would otherwise be restricted under ordinary copyright law. Artists can choose from a bundle of rights in copyright law (copyright, attribution, protection period, noncommercial purposes, and so on) to state how and in what ways they are willing to have others use their works. Likewise, people looking to use less-restricted material can find it available for use on the Creative Commons Web site: http://creativecommons.org/.
