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 configuration

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