The ImageFilter extension can prevent specific images from being rendered inline, similarly to MediaWiki:Bad image list. There is no option to allow the image on certain pages, but registered users can disable the filtering altogether.

Originally written for https://rationalwiki.org/ by User:Nx.

Usage

Put __NSFW__ on the description page of an image to filter it. Because the extension checks the source of the page only, this can't be in a template, but it can be inside a comment block so it doesn't appear on the rendered page.

Registered users can disable filtering using the checkbox in the Appearance/Files section of Preferences.

A listing of all image description pages tagged as NSFW can be viewed via Special:PagesWithProp and choosing the "imagefilter_nsfw" option from the "Property name" drop-down menu.
