I really don't think she requires that, Acadia. She only do not allow them used in commersial use, cause some of them are made out of brushes-freebies that do not allow commersial use. If she had required a on the images, I am sure she would have added the mark on them herself :) And you are right, she does not say anything about credit either, but I am sure she would be glad for a credit anyway :) She also have a section of free posercharacters there if I remember right, and maybe she still have her freebie-section here at Renderosity too :)
