I would definitely contact PuppyFind and report the illegal use. Because it is the web, you may have a little trouble but most sites will remove pictures if any issue is reported, right or wrong.
In the future, depending on the photo software you use, you can add a watermark on top of posted photos. That way, people visiting your website can see the pictures but whatever logo you choose will be displayed on them forever. If someone chooses to use one of them, every other person out there who sees it will see your website logo. The beauty of watermarks is you can save one folder of pictures with them and one folder without them for your private use.
Look into doing it, it is worth it and your pictures will never be stolen again. |
