To win an infringement suit, the artist must prove that he or she owned the copyright and the work was copied by the infringer. However, there are exceptions, such as fair use , compulsory licensing , and permission . There is a test for infringement as used by the courts. It is whether an ordinary person, looking at the original work and the work was altered in some way, but the ordinary observer test still leads to that most of the work has still been copied, then an infringement has taken place. Compulsory licensing was initially explained at the beginning of the paper where the copyright owner has no right to prevent the use of copyrighted work.
Permission is simple.
Another claim that a copyright owner may promulgate is the issue of unfair competition. The description of the unfair competition claim can be even broader. For example, artists can be prevented from being presented as the creator of works that they did not really create. The whole concept of reproducing an image is that more than one user will be able to take the digital file and use it. Unfortunately, in the real world, the proper channels of legally obtaining a copy and legally distributing an image are not always adhered to.
