Well, they have also taken a few images from my site. Maybe those people actually think that my Enclopedia-like images are actually done by Doug Drexler? Laz: Unfortunately there are far too many sites one the web that already use your images. When I was new to the web four years ago, I found them virtually everywhere, and, naive as I was in those days, I thought they were sort of "Freeware". Quite the opposite applies to Jim Stevenson's SSD. Everyone knows the images are from his site, although he did only a small part of them himself. So he mostly gets credit.
I guess if you kindly remind people of giving you credit, they will do so in 80% of all cases. I have only one very bad experience with a guy who copied my whole starship list, pretending that it was "Paramount copyright", and stuff from three other websites likewise. When I reminded him again (the third time) and told the other webmasters, he started uttering mean insults against me...
