I make my own....go to http://fineart.sk which is a human anatomy site for artists. There are some freebies but most you will have to pay for. They offer a huge selection of all kinds of human body shapes and sizes for male or female. They are done in front,back, and profile photographs of real human beans! Hi resolution photos at that. Get some and cut out and paste them over a character template and fill in the outer edges.If you line up the parts just right you will be amazed at the results. You may need to make a  few bump maps to add for realistic effects.Plus you can expand the photos to full size and capture just a 500x500 section of the skin and use it for an entire texture with the surface tab in Daz. Works great for me!
