Flow uses the WhatLinksHereProps hook (introduced in MW 1.24, gerrit #115860)to append "from the _header_; from a _post_" links after a Flow board reference in Special:WhatLinksHere. Nifty.
The "File usage" section of a File page doesn't have this extra information.

includes/ImagePage.php already runs an ImagePageAfterImageLinks hook, maybe Flow should hook into that; or ImagePage.php could run the WhatLinksHereProps hook the way includes/specials/SpecialWhatlinkshere.php does.
