When changing (for example prespective correction) an image on commons http://commons.wikipedia.org/wiki/Datei:example.jpg which is included in de-wiki, I found that I need to issue action=purge for the page http://de.wikipedia.org/wiki/Datei:example.jpg . A purge action on the including page or on the original file page did not help.
Summary:
In my view, action=purge for a page or an image should automatically refresh - observing server load issues - _all_ other occurences and inclusions of that image in others wikis, so that changed images are updated after a while without user intervention. I do not know the exact part of the software and the mechanism, how files from commons are included in local wikis like de-wiki. Can a developer please add such information to this bugzilla?
In de-wiki, this manual section http://de.wikipedia.org/wiki/Hilfe:Bilder#Nach_dem_Hochladen_einer_neuen_Bildversion should be reviewed/revised.
