I downloaded 3d nerds easy backdrop (which is supposed to be an "easy backdrop" tool that you can ad your own pictures to).  I use Daz Studio - the blank back drop loads, but the image files will not.  They are there, but do nothing.... I sent an email to nerd3d a week or so ago but have recieved no reply.  I believe it was a freebie, it is not in my account, but I also can not find it here when searching....
