Images may be two dimensional (e.g. a photograph) or three dimensional (e.g. a statue). They are typically 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 or illustration, e.g. a map, a graph, a pie chart, an abstract painting, etc. In this wider sense, images can also be produced manually (by drawing, painting, carving, etc.), by computer graphics technology, or a combination of the two (see pseudo-photograph).

A volatile image is one that exists only for a short period of time, e.g. the reflection of an object by a mirror, a projection of the sun on a wall by a pinhole camera, or a scene displayed on a cathode ray tube. A fixed image, also called hardcopy, is one that has been recorded on a material object, such as paper or textile. The word reflection (also spelt reflexion in British English) can refer to several different concepts: In mathematics, reflection is the transformation of a space. ...

Specialized meanings
The word also has many specialized meanings in various disciplines and contexts: - In geometric optics, a lens can produce a real image or a virtual image.
- In many other scientific and technical contexts, image usually means a two-dimensional signal—a physical phenomenon that can be modeled as a function from a two-dimensional domain (such as the plane or a rectangle) to some set of values, usually real numbers or vectors. This sense covers not only digital images but also analog ones, such as photographs. See image processing.
- In computer graphics and digital image processing, the word image almost always means digital image or, by extension, any computer description of an image, e.g. a raster map, an image file, or a 2D computer graphics model. For embedding an image in a webpage, see HTML element#Images. A number of standard test images are in use in the image processing literature which serve as a common test of various image processing algorithms.
- In computer science the word image can also mean an exact (bit-by-bit) copy of the contents of some device, such as a hard disk, floppy disk, CD-ROM, semiconductor storage chip, etc. In particular,
- A core image (or core dump, from magnetic core memory, the predominant RAM technology of the 1960s) is a faithful copy of the data stored in the main memory of a computer or process.
- An executable image is a structured file containing machine instructions and data, which can be loaded into a process's virtual memory and executed. See kernel (computers).
- A ROM image is a copy of the contents of an entire ROM chip, typically a video game executable, which may then be stored on another medium (in the case of copyrighted games, this comes under the category of software piracy).
- In mathematics, an image of a function consist of the output values of the mathematical function.
- In finance, the image is a coefficient (stock image) that bridges a stock's fundamental value and its market price.
- In philosophy, an image is a conception or idea.
- In religion, an image is an idol or icon, although these terms have very specialised meanings within certain sects and should not be held as always synonymous.
- In social psychology an image is a representation.
- In marketing image is often used as shorthand for the perception that consumers have for a brand, its values and its benefits (often referred to as brand image).
- Image Comics is an American publisher of comic books.
- The IMAGE spacecraft currently observing the Earth's magnetosphere
