The frame along with its mounts protects and often complements the artwork. Art work framed well will stay in good condition for a longer period of time. Joan Miró once did a work specifically to frame with a flea market frame, and many painters and photographers who work with canvas "gallery-wrap" their artwork, a practice wherein the image extends around the edges of the stretched canvas and therefore precludes use of a decorative picture frame. As picture frames can be expensive when purchased new, some people remove pictures from a frame and use the frame for other pictures.
