With theAControlImageLink extension, you can configure someuploaded 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. The image is a dick pic, and while potentially useful in medical articles, might not be especially appropriate in other contexts.
3. in conjunction withExtension:AccessControl - for some permission tweaks.

How this works:

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

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