Copyright is "default deny". Unless you've been granted specific permission to copy a copyrighted work you cannot copy it for any reason apart from a few very tightly defined "fair use" exceptions - criticism, parody, news reporting, research and scholarship, and teaching. And keep in mind that "works" include pictures or photographs and are are by default copyrighted to their creator. You con't need to "register your copyright", although it's smart to as a way to help prove ownership it's not a requirement. Any photo you take or picture(/texture) you draw automatically is copyright to you.
