Thing #3
As an artist and art teacher, I've had a lot of experience with fair use of art images. There is an interesting case that was in the national news involving Shepard Fairey's image of Obama on the presidential campaign's Hope poster. A major aspect of the case involved the artist's intent in his use of an AP photograph he used as a source for his portrait of Obama. The photographer had no objection to the use of his image. However, The AP threatened to file suit against Fairey as they claimed ownership of the image since the photographer was their employee. Fairey filed suit against the AP first claiming fair use.
