When a file such as an image or a video is uploaded to Wikipedia or the විකිමාධ්ය කොමන්ස් an associated file page is created. The purpose of these pages is to provide information about the file, such as who uploaded the file, any modifications that may have been made, an extended description about the file's subject or context, where the file is used, and licence or copyright information. In the case of an image, the file page shows a higher resolution version of the image (unless the image is very small).
The description page consists of five parts:
- The file itself
- Description of the file
- "File history" - when a new version of a file is uploaded with the same name, the existing file is replaced and becomes available via file history. See page history
- "File links" - a list of pages that embed the file. If the file is part of a template it lists only the template, not the pages in which the template is used (for that see "What links here" of the template).
- "Metadata" (images only) - technical information about the file and the equipment used to create it (camera model etc.)
The following are example pages for different types of files:
Useful things to include in the description sectionසංස්කරණය
The description section of the page is editable. Initially the description part automatically contains the upload summary supplied when the file was first uploaded. The following are useful things to put on a file page:
Eg: "Image of a goldfish in a small tank". This should not be an alternative text (see alternative text for images), but rather a description. This is useful for users who do not have direct access to the image, and is a temporary substitute for a proper
If you downloaded the file from somewhere else, you should give details of source, author, etc. See Wikipedia:Cite your sources.
All files must be provided with copyright information. This includes the author, the file's source and the file's license. All files must either be freely licensed or suitable for "fair use" (a low resolution image or only part of a song for example). You should choose the most appropriate tag from Wikipedia:Image copyright tags. Please be aware that the copyright holder (the original creator of the file, their employer, or an official designee), not the uploader, decides on the licensing for the image, and that "fair use" of non-free files has a specific definition. Please read Wikipedia:Copyrights, Wikipedia:Image use policy, Wikipedia:Fair use guideline, and Wikipedia:Image copyright tags for information about what images are acceptable to upload.

If other versions (especially a larger version) of the same file exists, link to them.

- [[Media:Goldfish-in-tank-textfree.jpg|textfree version]] ([[:Image:Goldfish-in-tank-textfree.jpg|info]])
Textfree versions are useful for using across language versions.
Most articles that use images will have a caption, but this will likely be shorter than the image's full description, and more closely related to the text of the article.
Keep in mind that everyone who sees this image in an article and clicks on it for more information (or to enlarge it) arrives at the file description page.
If you made the image yourself, there are certain questions which only you can answer. Because you may not be around to answer those questions later, you should include this information in the description page when you upload the image. This will help other editors to make better use of the image, and it will be more informative for readers.
- Where was the picture taken?
- When was the picture taken?
- What are the names of all the people and notable objects visible in the picture?
- What is happening in the picture?
- Who was the photographer?
For synthetic pictures:
- Diagrams and markings should be explained as completely as possible.
- If necessary, a legend or key should be provided.
Technical information for pictures:
- If a film camera was used, provide the model number, lense information and exposure settings
- What post-production modifications where made? (adjustments to color, contrast etc.)
Technical information for synthetic images:
- What software was used to create or edit the image?
- What pre-existing sources (free images, photos, etc) were used as inputs?
Files available on Wikipedia can be stored on Wikipedia or on විකිමාධ්ය කොමන්ස්. If a file is stored on Commons the following message will be shown on the file's description page: මෙම ගොනුව $1 වෙතින් වන අතර අනෙකුත් ව්යාපෘතීන් විසින්ද භාවිතා කල හැක. එහි [$2 ගොනු විස්තර පිටුව] තුල අඩංගු විස්තර මෙහි පහත දැක්වෙයි. Any edits to the file's description page should be made on Commons, except in special circumstances, such as indicating the file has reached featured status on Wikipedia. To edit the Commons description page click on the "description page there" link. Like Wikipedia, anyone can edit the Commons. An account is not required.
When editing, the Show preview function only shows the editable part of a file page. The file itself, the file history and the file links are not displayed.
Editing a fileසංස්කරණය
Files cannot be edited on Wikipedia or Commons. To edit a file it will need to be downloaded. Use a suitable software program (such as the GIMP or Photoshop for images) to perform the modifications. Once the changes are completed upload the file to Wikipedia or Commons. The same filename may be used. This will overwrite the existing file.
What happens when you uploadසංස්කරණය
The description text you supply during the upload process becomes the initial text of the image description page. (It also becomes the edit summary for the initial version of the file.)
On Wikipedia, please avoid adding a description in a language other than English. Instead, use interlanguage links to link to the image description page on the appropriate-language wiki, where you should upload a second copy of the image for local use.
On Commons, a translation may be added to the description page.
Uploading original imagesසංස්කරණය
If you have created an image yourself, and you have a higher-quality source file in a format such as .XCF, .PSD, or .AI, you may want to consider uploading that source file so that other users can more easily modify it if the need arises. Link the source file from the image description page. If the source file is too large to upload, try compressing it with a utility such as WinZip or gzip.
Wikipedia supports displaying SVG images, so it's generally best to upload SVG copies of images in place of raster renderings of them.
Files can be in the same category as other pages, but are treated separately: on the category page they are not included in the count of articles in the category, and they are displayed in a separate section, with for each a thumbnail and the name, see category page. A file category is typically a subcategory of the general category about the same subject, and a subcategory of a wider file category. On විකිමාධ්ය කොමන්ස් there are essentially only files.
For categorizing a new file, the file page does not even have to be edited: the category tag can simply be put in the upload summary. Many images can be categorized in one of the subcategories of Category:Wikipedia images by subject. You might need to poke around the category hierarchy a bit to find the right place.
File page locationසංස්කරණය
In English Wikipedia, the file page for a media file named F is at <http://si.wikipedia.org/wiki/File:F>, and it can be accessed using the Wiki markup
[[:File:F]]. A media file's name can be determined from its URL: it is always the URL's last or second-from-last component. For example, a flag image might have the following URL:
This URL's second-from-last component is "Flag_of_France.svg", so the corresponding file page is File:Flag_of_France.svg.
The URL of an image can often be determined by asking a browser to display the image's properties, and similarly for other media files. Sometimes, however, you may need to view the HTML of the page containing a media file to determine the file's URL. For example, in standard browsers the default English Wikipedia skin displays at upper left a puzzle-globe image, which takes you to the Main Page if you click on it; to find this image's file page, look in this page's HTML for the following:
- <a style="background-image: url(http://upload.wikimedia.org/wikipedia/en/b/bc/Wiki.png);" href="/wiki/Main_Page" title="Visit the main page"></a>
This HTML contains a URL whose last component is "Wiki.png", and the corresponding file page is therefore File:Wiki.png.
