Unfortunately, I contend with hundreds of copyright infringements every year. I have implemented the following policy in an attempt to maintain control over my work.
Unauthorized non-commercial uses of my copyrighted images and text online are subject to DMCA takedown requests without advance notice.
Unauthorized commercial infringements of my copyrighted images will be met with invoices covering my regular commercial-use fees (at a minimum of $95/image) plus a $50 infringement handling fee per image.
Infringement invoices are non-negotiable, and non-payment of infringement invoices will result in legal actions to recover statutory damage as outlined in Title 17, § 504, of the United States copyright laws.
All of my images are registered copyright with the U.S. copyright office.
