IMAGE

In common usage, an 'image' (from Latin ''imago'') or 'picture' is an artifact, usually two-dimensional, that has a similar appearance to some subject—usually a physical object or a person.
Images may be two-dimensional, such as a photograph or screen display, or three-dimensional such as a statue. They may be produced by optical devices—such as a cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water surfaces.
The word ''image'' is also used in the broader sense of any two-dimensional figure such as a map, a graph, a pie chart, or an abstract painting. In this wider sense, images can also be produced manually, such as by drawing, painting, carving, by computer graphics technology, or a combination of the two, especially in a pseudo-photograph.
A volatile image is one that exists only for a short period of time. This may be a reflection of an object by a mirror, a projection of a camera obscura, or a scene displayed on a cathode ray tube. A fixed image, also called a hardcopy, is one that has been recorded on a material object, such as paper or textile.
A mental image exists in an individual's mind: something one remembers or imagines. The subject of an image need not be real; it may be an abstract concept, such as a graph, function, or "imaginary" entity.
For example, Sigmund Freud claimed to have dreamt purely in aural-images of dialogues. The development of synthetic acoustic technologies and the creation of sound art have led to a consideration of the possibilities of a sound-image comprised of irreducible phonic substance beyond linguistic or musicological analysis.
A collection of non-volatile images providing an image changing with time is a film or motion picture.
