This is from their site About:
Period Images is the premier destination for high quality images traversing a wide range of genres from the past to the present.
It is our goal to provide you with hard to find, but affordable images reminiscent of a particular era for all your publishing needs.
*Do you know that Period Images does full production photo-shoots?
From the custom-made attires, to the hair, make-up and set design, Period Images is fully staffed with skilled artisans, digital artists, photographers and beautiful professional models with acting backgrounds, to depict 'scenes' and capture the essence of the era. That said, all of our images have Model and Property Releases. Not only that, but RVHC, our parent company which specializes in couture period fashion and products, also owns the Design Copyright and Trademark of all the attires we use, so you're guaranteed that you'll never end up with a cover image of models wearing cheap Halloween costumes found online, or in rental and seasonal stores.

This means you need to buy it before you can use it.
For those of you like me, who would like to add these to your Book Covers, EBanners, or EPost Cards, you can easily do it and for a great price. Superb pictures at a great price.
