Normally I wouldn't think to ask this question, because the photos that could potentially go in my book I've taken myself. But some of the photos are of individuals who posed for them.
So, I have their permission to take the photos, but do I need permission to put them in my book? In each case, the individuals are simply sitting or standing (fully clothed!) in an innocuous setting and they all look quite attractive and photogenic, so no problems with inappropriate content or looking embarrassingly bad. I'm not even sure if I know how to contact several of them, but would try, if necessary, or omit.
