Randal,

What I suggest you do is offer them for sale and describe them without posting photos. Then ask that potential buyers to send you an email and you will send samples. Be sure to watermark them. Better still, when you scan them, lay a strip of paper with "Randal's Pics" across the picture to discourage those who want a free collection.

Concentration camp photos have attracted unwanted attention and the occasional nut job in the past, so we'll pass on those the same as we pass on graphic battlefield remains.
