I've copied all of those images to an online folder. They are done by Oleg Volk, Professor, RKBA activist, photographer and founder of www.thehighroad.org and www.a-human-right.com
I have them online so I can use them as quick links for the web. Oleg is fine with reproduction of these images anywhere, no referencing necessary, as long as it is done to further the RKBA.
You can also find them and their hi-res versiona at www.olegvolk.net as well as a bunch of other neat photos. He does people pretty well.
