Fair use rationale for Heavy Rocks
Though this image is subject to copyright, its use is covered by the U.S. fair use laws because:
 * 1) The image is only a small portion of the overall product and serves as an easily identifiable part of a larger entity.
 * 2) The copy of the image is low-resolution and will not produce high-quality copies of the art for illegal duplication. The quality is high enough to clearly present the image and to place the subject represented by the image in a good light.
 * 3) The use of the image will not affect the value of the original work or limit the copyright holder's rights or ability to gain commercially from the work.
 * 4) It illustrates educational articles about the subject represented by the image.
 * 5) The image is used as the primary means of visual identification of topics in the article.
 * 6) It is not replaceable with an uncopyrighted or freely copyrighted image of comparable educational value.  A free image could not be created to replace it without itself being a derivative work.
