Image

== Cultural and other uses ==
Image-making seems to have been common to virtually all human cultures since at least the [[Paleolithic|paleolithic era]]. Prehistoric examples of [[rock art]]—including [[cave painting]]s, [[petroglyph]]s, [[rock relief]]s, and [[geoglyph]]s—have been found on every inhabited continent. Many of these images seem to have served various purposes: as a form of record-keeping; as an element of spiritual, religious, or magical practice; or even as a form of communication. [[History of writing|Early writing systems]], including [[Egyptian hieroglyphs|hieroglyphics]], [[Ideogram|ideographic]] writing, and even the [[Latin alphabet|Roman alphabet]], owe their origins in some respects to pictorial representations.

=== Meaning and signification ===
Images of any type may convey different meanings and sensations for individual viewers, regardless of whether the image's creator intended those. An image may be taken simply as a more or less "accurate" copy of a person, place, thing, or event. It may represent an abstract concept, such as the political power of a ruler or ruling class, a practical or moral lesson, an object for spiritual or religious veneration, or an object—human or otherwise—to be desired. It may also be regarded for its purely [[Aesthetics|aesthetic]] qualities, rarity, or monetary value. Such reactions can depend on the viewer's context. A religious image in a church may be regarded differently than the same image mounted in a museum. Some might view it simply as an object to be bought or sold. Viewers' reactions will also be guided or shaped by their education, class, race, and other contexts.

The study of emotional sensations and their relationship to the image falls into the categories of [[aesthetics]] and the philosophy of art. While such studies inevitably deal with issues of meaning, another approach to signification was suggested by the American philosopher, logician, and [[Semiotics|semiotician]] [[Charles Sanders Peirce]].

"Images" are one type of the broad category of "signs" proposed by Peirce. Although his ideas are complex and have changed over time, the [[Semiotic theory of Charles Sanders Peirce#II. Icon, index, symbol|three categories of signs]] that he distinguished stand out:

# The "'''icon'''," which relates to an object by resemblance to some quality of the object. A painted or photographed portrait is an icon by virtue of its resemblance to the painting's or photograph's subject. A more abstract representation, such as a map or diagram, can also be an icon.
# The "'''index'''," which relates to an object by some real connection. For example, smoke may be an index of fire, or the temperature recorded on a thermometer may be an index of a patient's illness or health.
# The "'''symbol'''," which lacks direct resemblance or connection to an object but whose association is arbitrarily assigned by the creator or dictated by cultural and historical habit, convention, etc. The color red, for example, may connote rage, beauty, prosperity, political affiliation, or other meanings within a given culture or context; the Swedish film director Ingmar Bergman claimed that his use of the color in his 1972 film ''[[Cries and Whispers]]'' came from his personal visualization of the human soul.<ref>{{cite web |last1=Matthew |title=Cries and Whispers (1972) |url=https://www.classicartfilms.com/cries-and-whispers-ingmar-bergman-1972 |website=Classic Arts Films |access-date=23 November 2023}}</ref>{{Relevance inline|date=November 2023}}

A single image may exist in all three categories at the same time. The [[Statue of Liberty]] provides an example. While there have been countless two-dimensional and three-dimensional "reproductions" of the statue (i.e., "icons" themselves), the statue itself exists as

* an "icon" by virtue of its resemblance to a human woman (or, more specifically, previous representations of the Roman goddess [[Libertas]] or the female model used by the artist [[Frédéric Auguste Bartholdi|Frederic-Auguste Bartholdi]]).<ref>{{cite web |last1=Hammond |first1=Gabriela |title=The Woman Behind the Statue of Liberty: Who Is Lady Liberty? |url=https://www.statueoflibertytour.com/blog/the-woman-behind-the-statue-of-liberty-who-is-lady-liberty/#:~:text=So%20who%20was%20the%20Statue,in%20the%20artist's%20own%20mind. |website=Statue of Liberty Tour |access-date=23 November 2023}}</ref>{{Better source needed|date=November 2023}}
* an "index" representing [[New York City]] or the United States of America in general due to its placement in [[New York Harbor]], or with "immigration" from its proximity to the immigration center at [[Ellis Island]].
* a "symbol" as a visualization of the abstract concept of "liberty" or "freedom" or even "opportunity" or "diversity".

=== Critiques of imagery ===
The nature of images, whether three-dimensional or two-dimensional, created for a specific purpose or only for aesthetic pleasure, has continued to provoke questions and even condemnation at different times and places. In his dialogue [[Republic (Plato)|''The Republic'']], the Greek philosopher [[Plato]] described our apparent reality as a copy of a higher order of universal [[Theory of forms|forms]]. As copies of a higher reality, the things we perceive in the world, tangible or abstract, are inevitably imperfect. Book 7 of ''The Republic'' offers Plato's "[[Allegory of the cave|Allegory of the Cave]]," where ordinary human life is compared to being a prisoner in a darkened cave who believes that shadows projected onto the cave's wall comprise actual reality.{{citation needed|date=November 2023}} Since art is itself an imitation, it is a copy of that copy and all the more imperfect. Artistic images, then, not only misdirect human reason away from understanding the higher forms of true reality, but in imitating the bad behaviors of humans in depictions of the gods, they can corrupt individuals and society.{{According to whom|date=November 2023}}

Echoes of such criticism have persisted across time, accelerating as image-making technologies have developed and expanded immensely since the invention of the [[daguerreotype]] and other photographic processes in the mid-19th century. By the late 20th century, works like [[John Berger|John Berger's]] ''[[Ways of Seeing]]'' and [[Susan Sontag]]'s ''[[On Photography]]'' questioned the hidden assumptions of power, race, sex, and class encoded in even realistic images and how those assumptions and how such images may implicate the viewer in the [[Voyeurism|voyeuristic]] position of a (usually) male viewer. The [[documentary film]] scholar [[Bill Nichols (film critic)|Bill Nichols]] has also studied how apparently "objective" photographs and films still encode assumptions about their subjects.

Images perpetuated in public education, media, and popular culture have a profound impact on the formation of such mental images:<ref>{{Cite web |last=Leupold |first=David |date=2020-04-08 |title=Image and ideology.

{{Blockquote|text=What makes them so powerful is that they circumvent the faculties of the conscious mind but, instead, directly target the subconscious and affective, thus evading direct inquiry through contemplative reasoning. By doing so such axiomatic images let us know what we shall desire (liberalism, in a snapshot: the crunchy honey-flavored cereals and the freshly-pressed orange juice in the back of a suburban one-family home) and from what we shall obstain (communism, in a snapshot: lifeless crowds of men and machinery marching towards certain perdition accompanied by the tunes of Soviet Russian songs).

=== Religious critiques ===
Despite, or perhaps because of, the widespread use of religious and spiritual imagery worldwide, the making of images and the depiction of gods or religious subjects has been subject to criticism, censorship, and criminal penalties. The [[Abrahamic religions]] ([[Judaism]], [[Christianity]], and [[Islam]]) all have had admonitions against the making of images, even though the extent of that proscription has varied with time, place, and sect or denomination of a given religion. In Judaism, [[Thou shalt not make unto thee any graven image|one of the Ten Commandments]] given by God to Moses on Mount Sinai forbids the making of "any graven image, or any likeness [of any thing] that [is] in heaven above, or that [is] in the earth beneath, or that [is] in the water under earth." In Christian history, periods of [[iconoclasm]] (the destruction of images, especially those with religious meanings or connotations) have broken out from time to time and some sects and denominations have rejected or severely limited the use of religious imagery. Islam tends to discourage religious depictions, sometimes quite rigorously, and often extends that to other forms of realistic imagery, favoring [[calligraphy]] or [[geometric design]]s instead. Depending on time and place, photographs and broadcast images in Islamic societies may be less subject to outright prohibition. In any religion, restrictions on image-making are especially targeted to avoid the depictions of "false gods" in the form of [[Idolatry|idols]]. In recent time, [[militant]] extremist groups such as the [[Taliban]] and [[Islamic State|ISIS]] have destroyed centuries-old artifacts, especially those associated with other religions.

===In culture===
Virtually all cultures have produced images and applied different meanings or applications to them. The loss of knowledge about the context and connection of an image to its object is likely to result in different perceptions and interpretations of the image and even of the original object itself.

Through human history, one dominant form of such images has been in relation to religion and spirituality.{{Weasel inline|date=November 2023}} Such images, whether in the form of [[Idolatry|idols]] that are objects of worship or that represent some other spiritual state or quality, have a different status as artifacts when copies of such images sever links to the spiritual or supernatural. The German philosopher and essayist [[Walter Benjamin]] brought particular attention to this point in his 1935 essay "The Work of Art in the Age of Mechanical Reproduction."<ref>{{cite journal |last1=Benjamin |first1=Walter |title=The Work of Art in the Age of Mechanical Reproduction |url=https://web.mit.edu/allanmc/www/benjamin.pdf|journal= Illuminations |location=New York |publisher=Schocken Books |year=1969}}</ref>

Benjamin argues that the mechanical reproduction of images, which had accelerated through photographic processes in the previous one hundred years or so, inevitably degrades the "authenticity" or quasi-religious "aura" of the original object. One example is [[Leonardo da Vinci]]'s ''[[Mona Lisa]]'', originally painted as a portrait, but much later, with its display as an art object, developed a "cult" value as an example of artistic beauty. Following years of various reproductions of the painting, the portrait's "cult" status has little to do with its original subject or the artistry. It has become famous for being famous, while at the same time its recognizability has made it a subject to be copied, manipulated, satirized, or otherwise altered, in forms ranging from [[Marcel Duchamp|Marcel Duchamp's]] [[L.H.O.O.Q.|''L.H.O.O.Q''.]] to [[Andy Warhol]]'s multiple [[Screen printing|silk-screened]] reproductions of the image.<ref>{{cite web |url=https://www.metmuseum.org/art/collection/search/489409 |website=The Met|title=Mona Lisa|author=Warhol, Andy  |publisher=The Metropolitan Museum of Art}}</ref>{{Better source needed|date=November 2023}}

In modern times, the development of "[[non-fungible token]]s" (NFTs) have been touted as an attempt to create "authentic" or "unique" images that have a monetary value, existing only in digital format. This assumption has been widely debated.{{citation needed|date=November 2023}}
