Wikipedia contains millions of illustrative images and other electronic media. This page gives a very brief overview of how images are used in Wikipedia; for more information, see Image use policy and see Help:Files on how to upload and include an image.

[সম্পাদনা]উপযোগিতা এবং বিশ্বকোষীয় প্রকৃতি
[সম্পাদনা]Images must be relevant to the article that they appear in and be significantly and directly related to the article's topic. Because the Wikipedia project is in a position to offer multimedia learning to its audience, images are an important part of any article's presentation. Effort should therefore be made to improve quality and choice of images or captions in articles rather than favoring their removal, especially on pages that have few visuals.
Images are primarily meant to inform readers by providing visual information. Consequently, images should look like what they are meant to illustrate, even if they are not provably authentic images. For example, a photograph of a trompe-l'œil painting of a cupcake may be an acceptable image for Cupcake, but a real cupcake that has been decorated to look like something else entirely is less appropriate. Similarly, an image of an unidentified cell under a light microscope might be useful on multiple articles, as long as there are no visible differences between the cell in the image and the typical appearance of the cell being illustrated.
Articles that use more than one image should present a variety of material near relevant text. If the article is about a general subject for which a large number of good quality images are available, (e.g., Running), editors are encouraged to seek a reasonable level of variety in the age, gender, and race of any people depicted. Adding multiple images with very similar content is less useful. For example, three formal portraits of a general wearing his military uniform may be excessive; substituting two of the portraits with a map of a battle and a picture of its aftermath may provide more information to readers. You should always be watchful not to overwhelm an article with images by adding more just because you can.
Poor quality images (too dark, blurry, etc.) or where the subject in the image is too small, hidden in clutter, ambiguous or otherwise not obvious, should not be used. Contributors should be judicious in deciding which images are the most suitable for the subject matter in an article. For example:
- An image of a white-tailed eagle is useless if the bird appears as a speck in the sky.
- Gloria Steinem looks best as a portrait photograph of herself alone, not with other individuals.
- A suitable picture of a hammerhead shark would show its distinctive hammer-like head, to distinguish it from other species of shark.
- A map of Moldova should show its frontiers with Romania and Ukraine, so people may know where the country is located in relation to its neighbors.
- Rice is best represented with an image of plain rice, not fried rice.
- Intangible concepts can be illustrated; for example, a cat with its claws out portrays aggression.
Avoid entering textual information as images
[সম্পাদনা]Do not use images to express textual information in place of real text. See Avoid entering textual information as images for more.
আক্রমণাত্মক চিত্র
[সম্পাদনা]Including information about offensive material is part of Wikipedia's encyclopedic mission. Wikipedia is not censored. However, images that can be considered offensive should not be included unless they are treated in an encyclopedic manner. Material that would be considered vulgar or obscene by typical Wikipedia readers[nb ১] should be used if and only if its omission would cause the article to be less informative, relevant, or accurate, and no equally suitable alternative is available. Per the Foundation, controversial images should follow the principle of 'least astonishment': we should choose images that respect the conventional expectations of readers for a given topic as much as is possible without sacrificing the quality of the article. Avoid images that contain irrelevant or extraneous elements that might seem offensive or harassing to readers. For example, photographs taken in a pornography context would normally be inappropriate for articles about human anatomy.
ভূমিকার জন্য চিত্র
[সম্পাদনা]It is very common to use an appropriate representative image for the lead of an article, often as part of an infobox. The image helps to provide a visual association for the topic, and allows readers to quickly assess if they have arrived at the right page. For most topics, the selection of a lead image is plainly obvious: a photograph or artistic work of a person, photographs of a city, or a cover of a book or album, to name a few.
Image selection for other topics may be more difficult and several possible choices could be made. While Wikipedia is not censored, as outlined in the above section on offensive images, the selection of the lead image should be made with some care with respect to this advice. Lead images are loaded and shown upon navigating to the page, and are one of the first things that readers will see. Editors should avoid using images that readers would not have expected to see when navigating to the page. Unlike other content on a page that falls below the lead, the lead image should be chosen with these considerations in mind.
Some advice on selecting a lead image include the following:
- Lead images should be images that are natural and appropriate visual representations of the topic; they not only should be illustrating the topic specifically, but should also be the type of image that is used for similar purposes in high-quality reference works, and therefore what our readers will expect to see. Lead images are not required, and not having a lead image may be the best solution if there is no easy representation of the topic.
- Lead images should be selected to be of least shock value; if an alternative image exists that still is an accurate representation of the topic but without shock value, it should always be preferred. For example, using an image of deportees being subjected to selection as the lead image at this version of Holocaust is far preferable to the appropriate images that appear later in the article that show the treatment of the prisoners or corpses from the camps.
- Sometimes it is impossible to avoid the use of a lead image with perceived shock value if the topic itself is of that nature, for example in articles on various parts of human genitalia. It should be anticipated, through Wikipedia:Content disclaimer, that readers will be aware they will be exposed to potentially shocking images when navigating to articles on such topics.
- Articles about ethnic groups or similarly large human populations should not be illustrated by a photomontage or gallery of images of group members; see this RfC.
The first image in an article, regardless of whether it is placed in the lead, will be enlarged and displayed at the top of all articles viewed in the Android mobile app. For example, if the first image in an article about Theft is a person, then that person's picture will be displayed as if it were the lead image, even if the image displays at the end of the article in the desktop view. When selecting images for the article, consider whether the order of the images may inadvertently produce a non-neutral, unfair, or otherwise poor educational experience for readers who use mobile devices.
চিত্রের জীবন চক্র
[সম্পাদনা]Eventually, some of the images reach the end of their life cycle. They may be superseded or replaced by an image with a friendlier copyright policy. If you come across an image that needs to be removed due to copyright, invasion of privacy, or other serious reasons, then list it on Files for deletion. However, superseded images should be kept to preserve Wikipedia's historical record. The history of articles can be difficult to assess if images and templates have been deleted over the years.
Conversely, if you have contributed or found an image that stands out from the crowd, you are invited to nominate it for inclusion on the Featured pictures list.

To produce this box, use:
[[File:Example.png|thumb |alt=Example alt text |Example caption]]
To incorporate an image into an article (either a local image or any image that is at the Wikimedia Commons), you will need to use image syntax. Note that if an identically named file exists on Wikipedia and on Commons, it's not possible to link to the file on Commons as the syntax is same and the local file has higher priority. As an example in a simple form, in order to reproduce the image at the top of this page, insert the following text into an article:
- The first parameter is the page name of the file page (e.g.
File:Example.png
). You must reproduce the exact name of the image file including its capitalization, spacing and not omit its file extension such as.jpg
. - The second "
thumb
" parameter forces the creation of a thumbnail, and must be in lower case. - The third parameter, "
alt=Example alt text
", can be modified to specify suitable alt text. Alt text is meant for readers who cannot see the image. It summarizes the image's appearance, not its meaning, and is therefore unlike the caption. Alt text also helps search engines find Wikipedia articles. - The last parameter, "
Example caption
", can be replaced with any suitable caption.
Additional points:
- The full set of options is more complex; however, the vast majority of images should be able to be displayed by using the above format.
- If the image does not show up and you are sure the syntax is correct, it may have been blacklisted. See MediaWiki:Bad image list for a list of such images.
- The "File:" prefix may be used interchangeably with "Image:":

[সম্পাদনা]- "
upright=1.2
" (or "|frameless|upright=1.2
" for plain pictures) resizes an image to approximately the given multiple of a user's preferred width. An image should generally be no more than "upright=1.8
" (defaults to 400 pixels) wide; an image can be wider if it uses the "center
" or "none
" options to stand alone. e.g.
- Alternatively, a fixed size can be specified in the form
|XXXpx
, where XXX is replaced by a number of pixels, although this should be avoided where possible, since it overrides the user's default. For example: টেমপ্লেট:Xt2- As a general rule, images should not be set to a larger fixed size than the 220px default (users can adjust this in their preferences). If an exception to the general rule is warranted, forcing an image size to be either larger or smaller than the 220px default is done by placing a parameter in the image coding.
- Lead images should usually be no wider than "upright=1.35" (displays at 300px based on the default thumbnail width of 220px, but may appear larger or smaller based on settings in preferences).
- In addition to the width restrictions, with the default value, larger images should generally be a maximum of 500 pixels tall, so that they can comfortably be displayed on the smallest displays in common use. This can be done by proportionately reducing the width.
- Images in which detail is relatively unimportant (for example, a national flag) can be smaller than usual.
- Images containing important detail (for example, a map, diagram, or chart) may need larger sizes than usual to make them readable.
- Images in which a small region is relevant, but cropping to that region would reduce the coherence of the image, may need to be larger than normal.
- Large, panoramic images, may require larger sizes to make them viewable or readable.
- Images should be large enough to reveal relevant details without overwhelming the surrounding article text.
- The {{wide image}} and {{tall image}} templates display images that would otherwise be unreasonably wide or tall in a scrollable box.
- Similar types of images within an article often look appealing if they appear at the same pixel size.
অবস্থান
[সম্পাদনা]Images should not be placed in the middle of paragraphs. An image within a paragraph forces the rendered text to break at that point, causing a disruption of text flow and problems for any readers whose browsers do not display images.
অনুভূমিক স্থাপন
[সম্পাদনা]- In most cases, images should be right justified on pages, which is the default placement. If an exception to the general rule is warranted, forcing an image to justify on the left side of a page is done by placing a parameter in the image coding in the form
|left
, for example:
- Multiple images in the same article can be staggered right-and-left to improve balance of the article. However, avoid sandwiching text between two images that face each other, or between an image and infobox, navigation template, or similar. If multiple related images are being placed on the right, then the {{multiple image}} template may be useful.
- In a few web browsers, bulleted lists overlap with left-aligned images. It may be preferable to avoid placing a left-aligned image near lists.
It is often preferable to place images of faces so that the face or eyes look toward the text. However, images of people ought not be reversed to make the person's face point towards the text, because faces are generally asymmetrical. Reversal may result in materially misleading the viewer (e.g., by making the subject of the article or section appear to have a birthmark on the left side of his face, when the birthmark is actually on the right side).
উল্লম্ব স্থাপন
[সম্পাদনা]An image should generally be placed in the section of the article that is most relevant to the image. Avoid referring to images as being on the left or right. Image placement is different for viewers of the mobile version of Wikipedia, and is meaningless to people having pages read to them by assistive software. Instead, use captions to identify images.

[সম্পাদনা]- For further information, see: m:Help:Preferences
Logged in users can set their default viewing size of thumbnails in the "my preferences" area under "appearance", which offers an opportunity to customize "files". The default size for users that are not logged in is 220 pixels. Logged in users can choose from widths between 120px and 400px. Also under "files" in the "appearance" tab of "my preferences" area, one can set the size limit of images shown on image description pages. By default, if either the width or the height exceeds 800px or 600px respectively, then the image is reduced in size until it fits within those dimensions. This can be enlarged.
Making images available
[সম্পাদনা]- For further information, see: Extended image syntax, Embedding Commons' media in Wikipedia articles as well as Uploading images
Images uploaded to Wikipedia are automatically placed into the file namespace, formerly known as the image namespace. This means that names of image pages start with the prefix "File:".
