Hey, it looks like that website is hosted by HostGator...which is a good thing as I work for the HostGator Security department and can make a suggestion. I would highly recommend that you send a DMCA notice to our department, where it will be investigated and taken down as required by law. You or your lawyer can easily fill out the DMCA form online. Alternatively you can follow the guide we have for sending DMCA notices via fax or letter.
It often won't be productive to contact the webmaster of such sites as they usually feel any image hosted on the internet is fair game. However, if you contact their hosting providers (by looking up their IP and performing a whois search on it) or even their upstream providers, chances are fairly good that you'll be able to have your works taken down.
Honestly, a letter from a lawyer on your behalf would probably lead to a settlement without any need for a lawsuit. That being said, maybe we need a very public case in order to make this problem more widely known (though chances are this case would never make it to trial).
Thanks man, not sure if i want to become the public face of this issue for artists, esp against someone known to have such deep pockets, although this wouldnt be an issue about money for me, i am very afraid that such an event would put me off my making 'stuff' altogether.
lol Discovery Channel did that to me... I eventually found out who did it and got compensation... apparently a lot of these companies send out to a graphics company to create their graphics, and assuming of course that they company is using legitimate images. It took me 3 weeks to get answers. I hope you find out who did this and get the money you deserve.
