The PLUS Picture Licensing Glossary lists industry standard definitions for words and phrases used in communicating and managing the rights associated with photography, illustration, and other artworks. The Glossary is the core of an integrated system of standards that exist as a comprehensive resource for use by every professional engaged in creating, distributing, using or preserving images, so that we all may speak a common language, avoid misunderstandings, and achieve a precise mutual understanding of the scope of the rights associated with any image.
