Check usage and version matrix.

With the AControlImageLink extension, you can configure some uploaded image to be includable (via [[File:Name.png|thumb]]) only into the pages where you allow this image to be.

Possible uses:

  1. the image contains spoilers for the movie, and you want to show it only on pages that are marked as "Can contain spoilers" (and have Disclaimers/Warnings). If so, you can allow this image to be included only into these whitelisted pages.
  2. in conjunction with Extension:AccessControl - for some permission tweaks.

How this works:

  1. If File:Something.pdf has <accesscontrol>HasSpoilers</accesscontrol>, then articles without this exactly the same accesscontrol tag won't render [[File:Something.pdf]] syntax. (a link to image description page is shown instead of thumbnail)
  2. Files without accesscontrol tag are not restricted.
  3. Only files with extensions listed in $wgAControlImageLinkRestrictedExtensions array (default: empty) are restricted.

Sample configurationEdit

wfLoadExtension( 'AControlImageLink' );
$wgAControlImageLinkRestrictedExtensions = [ 'pdf' ];


  • Download and place the file(s) in a directory called AControlImageLink in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'AControlImageLink' );
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
