How To Upload Files To Your Wiki

Updated: Oct 30

MediaWiki File Upload Restrictions

MediaWiki configuration may restrict your ability to upload files:

  • by file size (defaults to 2Mb)

  • by file type (defaults to popular image formats: [ 'png', 'gif', 'jpg', 'jpeg', 'webp', ])

A warning about current settings are shown in Special:Upload – a standard MediaWiki interface for files uploading.


Both values can be adjusted to your particular wiki by administrators or developers in config files.


Authorship

Uploaded files may have copyright implications and require an appropriate attribution. Each file has its own page that can be edited like any regular wiki page, so say your kudos to the file authors / creators there. The list of licenses can be adjusted to your needs on Mediawiki:Licenses by users belonging to the interface administrators group. If you are unfamiliar with MediaWiki User Groups, you can read more about them here.

Standard File Upload Workflow

The standard MediaWiki file uploading is done via the Special:Upload on the wiki. Its interface allows:

  • to select a file in your computer filesystem: Source filename

  • to adjust the file name: Destination filename

  • to input the text that will be preloaded to the file page: Summary

  • to choose the license, if necessary: Licensing

  • to force uploading even if duplicates are found: Ignore any warning


MediaWiki File Upload Interface

MediaWiki File Page

Once you click the Upload file button, a page with the preloaded text and the image preview will be created. The page also contains:

  • a link for re-uploading the file,

  • a table with the history of file versions,

  • a list of pages that reference this file,

  • an expandable section with the file metadata


MediaWiki File Upload Extension

There are extensions that can modify upload process to match different use cases:

  • UploadWizard

  • MsUpload

  • SimpleBatchUpload

MediaWiki File Upload Tips

  1. The uploaded file can be inserted into content pages using VisualEditor or wiki markup

  2. All uploaded files can be seen in Special:ListFiles

  3. All file pages have File: prefix, or we are used to say "belong to the File namespace".

  4. Use semantically rich names for your files rather than technical names. Good: Election worker Hazel Rountree explains how to place a ballot in the optical scanner.jpg Bad: 1.jpg

Uploading files to a wiki is a fairly straightforward process. Still, the process can get tricky if you are looking to install and configure extensions for bulk uploads or other customizations.
