Understanding the basics of copyright law is critical for graphic designers because they use the work of other creative venues such as photographers, copy writers, illustrators, and work provided by the client. If you use work that infringes on the rights of another creative professional you can sued. Clients also provide work to be used in work they are asking you to do. In that case it must be made clear (in writing) that it will be assumed the client has permission to use all work they provide.
