Issues Open tasks · Report a bug

MediaUploader is a flexible file upload tool forked from UploadWizard.


  • Your MediaWiki will need to be capable of hosting media files and creating thumbnails (smaller previews of media files). If you can upload images and see smaller previews on their File page, you're already ready. If not, for full instructions, see Manual:Image administration, particularly image thumbnailing.
  • Download and place the file(s) in a directory called MediaUploader in your extensions/ folder.
  • Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See task T173141 for potential complications.)
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'MediaUploader' );
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Updating from UploadWizardEdit


Development statusEdit

We are currently identifying and resolving issues that should be fixed before the initial release. Until then, the extension may change a lot and break compatibility, so using it is not recommended for now. See this Phabricator task for more details.

Origin and designEdit

The idea of MediaUploader stemmed from the numerous issues with using UploadWizard on third-party wikis. The original tool was mostly designed for use by Wikimedia Commons, fulfilling its very specific needs (e.g. Wikibase support, specific licensing hacks, image-based tutorials). Third parties usually have a very different set of requirements that emphasize simplicity and flexibility. The two approaches are hard to reconcile in a single extension, especially given that UploadWizard must meet Commons' requirements and has no obligation to consider the needs of third parties. Thus, MediaUploader was born.

Main design goals of MediaUploader are:

  • Ease of use, at least as good as the original UploadWizard.
  • Configurability of all elements, well-described in documentation.
  • Ability to simplify certain elements of the wizard for wikis with less strict image description requirements.
  • Extensibility to allow for wiki-specific enhancements to be created locally.
  • No Wikimedia Commons-specific features.
