Editors can exclude **any file** (images of all kinds, PDFs, …) from search
engine indexing directly in the **File list** module — one checkbox in the
file metadata, no matter where the file is used and without a developer.

The extension serves a dynamically generated :file:`robots.txt` that contains
``Disallow`` entries for every marked file — the original file **plus** its
processed variants. Blocking via :file:`robots.txt` is the
`way officially recommended by Google
<https://developers.google.com/search/docs/crawling-indexing/prevent-images-on-your-page>`__
to keep images out of Google Image Search.
