Stock photography is the supply of photographs, which are often licensed for specific uses.

The stock photo industry, which began to gain hold in the 1920s, has established models including traditional macrostock photography, midstock photography, and microstock photography.

Conventional stock agencies charge from several hundred to several thousand American dollars per image, while microstock photography may sell for around USD 25 cents.

Professional stock photographers traditionally place their images with one or more stock agencies on a contractual basis, while stock agencies may accept the high-quality photos of amateur photographers through online submission.

Royalty-free, or RF, refers to the right to use copyright material or intellectual property without the need to pay royalties or license fees for each use or per volume sold, or some time period of use or sales.

The term public domain has two senses of meaning.

Anything published is out in the public domain in the sense that it is available to the public.

Once published, news and information in books is in the public domain, although they may also be copyrighted.

In the sense of intellectual property, works in the public domain are those whose exclusive intellectual property rights have expired, have been forfeited, or are inapplicable.

For example, the works of Shakespeare and Beethoven, and most of the early silent films, are all now in the public domain by either being created before copyrights existed or leaving the copyright term.

Examples for works not covered by copyright which are therefore in the public domain, are the formulae of Newtonian physics, cooking recipes, and all software before 1974.

Examples for works actively dedicated into public domain by their authors are reference implementations of cryptographic algorithms, NIH's ImageJ, and the CIA's World Factbook.

The term is not normally applied to situations where the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or "with permission".

Vector graphics is the use of polygons to represent images in computer graphics.

Vector graphics are based on vectors, which lead through locations called control points or nodes.

Each of these points has a definite position on the x- and y-axes of the work plane and determines the direction of the path; further, each path may be assigned various attributes, including such values as stroke color, shape, curve, thickness, and fill.

A digital image is a numeric representation of (normally binary) a two-dimensional image.

Depending on whether the image resolution is fixed, it may be of vector or raster type.

By itself, the term "digital image" usually refers to raster images or bitmapped images.
