If you like "creating beauty" why don't you get your own camera and create! Or get permission to use, rather than to steal other person's property and have your company make money doing so. After-all, I am sure that your aim in this case is not altruistically to enlarge the world's stock of beautiful pictures!
We often see members edit other members images posted on this site. I often do this myself. However, this is not done in any commercial venture, simply to illustrate how another person could edit the image. After-all, for all of us, this is a learning, not an earning site, as well as an enjoyable site to visit.
Sorry if I came across pretty strong. Intellectual property is one on my sore points...

Well said, Tom - exactly why I presented the OP with an out-of-focus image to play with. Was probably being too subtle with that, though. :(
