Another good site is PETA's collegeactivist.com. In addition to good advice on starting a college animal rights group, they also have a page of downloadable resources.

The Animal Liberation Front Information Service maintains the Frontline Image Archive. This huge archive includes (as of this writing) 125 images in categories like animal liberation, fur farm actions, economic damage, animal abusers, animals, and animal art. Images are free to non profit animal groups with photo credits.

If you know of any other animal rights resource sites please let me know! Contribute to the collective.
