A number of years ago I found my Hoya carnosa photo in use on the world of succulents website; they'd cropped the photo to remove my watermark and I contacted them and told them to either remove my photo or credit me as the owner. They never, ever responded and I just looked and the picture is still there but now below the picture it says:
Via Dave's Garden. I haven't been a member at DG for years but I still have photos in the database there.
