We have this
Given a filename exists on commons, but doesn't on another wiki website, one can visit that filename on the other website and it'll load the version from Commons.
E.g. https://en.wikipedia.org/wiki/File:2019-01-13_Commons_Structured_data_captions.png is actually https://commons.wikimedia.org/wiki/File:2019-01-13_Commons_Structured_data_captions.png
This currently includes MediaInfo content, but since MediaInfo is not installed on those wikis, it doesn't have any of the styling, the tabs, the interactivity, ...
We want this
We don't want MediaInfo content to show up on any other wiki than Commons.
Acceptance Criteria
Example: https://en.wikipedia.org/wiki/File:2019-01-13_Commons_Structured_data_captions.png
- MediaInfo content (captions and statements) should not be shown on non-Commons pages that include a file from Commons.
