File on Wikipedia means an , a video clip, or an audio clip, including document length clips. Here the term file can mean the data file itself, or the title of a file page (or description page). The file page contains a comprehensive description of the file so that a search result will produce all files related to the descriptive search terms you enter.
for data files on Wikipedia, or upload your own file. (See Uploading files below.) To find an image enter "File:search terms" into the search box. Your search results will include every search term found on the description pages, which all have titles that begins with the word File followed by a colon. Knowing the page name you can then link to it in the wikitext. (See Using files below.) For example, the page named File:Wikipedesketch1.png will appear in the search results for ".
There are three variants of links to files:
The preferred formats
High resolution images and animated .gif files may pose a problem for performance, but see the problem description in terms of bandwidth and reader's computing power at Consideration of image download size. For photographs in JPEG format, upload the best quality and highest resolution version available; these will be automatically scaled down to low-resolution thumbnails when needed.
Once the file is uploaded, please verify its file page image quality and description, considering how it key words help tag it for proper indexing in a . If a file of the same name exists on both Wikipedia and Commons, the Wikipedia file will be displayed.
Copyrighted materials cannot be uploaded to either location; see Image use policy. Files subject to any restrictions whatsoever, even "for use on Wikipedia only", . In case an image is , use low-resolution, low-bandwidth files.
for and find one of many existing image files, or upload your own file. Knowing the file's page name you can then edit your page and refer to that file to insert it into your wikitext. You will wikilink the page name, which will in turn include its file (of that name) in the page you edit. Take for example File:Wikipedesketch1.png. Use the following all on one line (with no line breaks). Then the results will be as shown in the image to the right:
By default, the page layout will place the image to the right of the wikitext, one line below where you placed the link. The extended image syntax provides many options to control how an image is displayed. You can make it "float" to the left, or center it, or place it without text flowing around it. You can force its size (to differ from the default set by the user), or even provide for the reader move around in a panorama. You can avoid image "stackups" in several ways, for example, by alternating left and right images, by aligning images, and if all else fails by forcing a break. You can create a gallery of images arranged into an array by using table syntax, (see ), and by using a gallery tag. (Gallery tags do not support alt text, so they generate galleries that will not be accessible to readers who cannot see the images) Also, you can create plain pictures that do not have captions and can be mingled with text and other images; these can use more fine-grained techniques, including borders, vertical alignment with text, and control over links. You can also link to an image without displaying it.
For examples of all these techniques, see ''Picture tutorial.
To avoid accidental overwriting of images or other media, generic filenames should not be used when uploading. For example, a picture of an album cover should not be given the name File:Cover.jpg. Sooner or later someone else will try to do the same thing, and that could overwrite the old image. Then the new image will appear wherever the old one was seen before—an album article would then show the wrong album cover.
The request to rename a page is made by adding the following template to the wikitext file page, anywhere on the page:
The most common and accepted reasons a file mover will change a name are:
