The latest information that I have regarding United States copyright protection indicated that while one can file a formal application for copyright registration with the government, it isn't necessary to formally do so. The signature of the artist of an orginal work on indicated work will serve to indicate that the image is a copyrighted image with the ownership of said copyright residing with the artist.

The latest information that I have available indicated that the ownership of said copyright will reside for the lifetime of the artist plus a period of twenty five years.
