I take a lot of photos, but some of my work involves manipulation of the work of others. In general, I try to use images from press releases, images where copyright has expired or has been ceded to the public domain, or my treatment of the image has transformed the image and has added substantial scientific or artistic value to it. Some images have been shrunk into thumbnail sizes, a process which has survived recent court challenges as fair use. In general I think I toe the line of fair use, but then again I am not a lawyer. If you are the copyright owner of an image that you feel is being misused, please contact the site admin. We should be able to come to an agreement that is mutually beneficial.
