Advertising
Advertising is an audio or visual form of marketing communication that employs an openly sponsored, non-personal message to promote or sell a product, service or idea. Sponsors of advertising are typically businesses wishing to promote their products or services. Advertising is differentiated from public relations in that an advertiser pays for and has control over the message. It differs from personal selling in that the message is non-personal, i.e., not directed to a particular individual. Advertising is communicated through various mass media, including traditional media such as newspapers, magazines, television, radio, outdoor advertising or direct mail; and new media such as search results, blogs, social media, websites or text messages. The actual presentation of the message in a medium is referred to as an advertisement or "ad" for short.
Design
Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
Graphics
Graphics (from Greek γραφικός graphikos, "belonging to drawing") are visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone to inform, illustrate, or entertain. In contemporary usage it includes: a pictorial representation of data, as in computer-aided design and manufacture, in typesetting and the graphic arts, and in educational and recreational software. Images that are generated by a computer are called computer graphics.
Image
An image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.
Design
One of the best ways to economize in building is to economize on ugliness. ...Nothing can be greater service in avoiding ugliness than a knowledge of the principles of design.
Ernest Flagg, Small Houses: Their Economic Design and Construction (1922)
Image
I believe that robotic thinking helps precision of psychological thought, and will continue to help it until psychophysiology is so far advanced that an image is nothing other than a neural event, and object constancy is obviously just something that happens in the brain.

Advertising
There are a lot of great technicians in advertising. And unfortunately they talk the best game. They know all the rules. They can tell you that people in an ad will get you greater readership. They can tell you that a sentence should be this short or that long. They can tell you that body copy should be broken up for easier reading. They can give you fact after fact after fact. They are the scientists of advertising. But there's one little rub. Advertising is fundamentally persuasion and persuasion happens to be not a science, but an art.
