People in all cultures all over the world understand stealing is wrong. This includes people in eastern Europe and people from developing countries. The fact that somebody would go to the trouble of removing the photographer's watermark and replacing it with their own, pretending the image is their own, proves they understand they are stealing. If they are willing to steal other people's images and replace identifying information with their own, they are not going to be honest in business, either. All a person has to do is request permission from the original author, who will often agree. The author's name is clearly shown on the PBS Wiki, along with contact information for those maintaining the Wiki. If the author refuses permission to use the image the person needs to find the image somewhere else. Leo Martin Phoenix Arizona USA
