http://www.deepangel.com/html/contact_us.html This is the link to the contact page. There are a number of different emails there. I would suggest just contacting the managers privately and asking about the situation. Perhaps they are not using the free items for any commercial use at all and are only claiming copyright to the image itself. In any case, it would be best to ask the managers it may all just be a misunderstanding. Best to figure it out privately and promptly.
