I suggest you send a link to it via MassMessage to https://www.wikidata.org/wiki/Q5413052#sitelinks-wikipedia (they typically have 100-200 watchers on big Wikipedias) 

Thanks for the advice! I've created m:User:Tgr_(WMF)/MediaViewer_template_spamlist and m:User:Tgr_(WMF)/MediaViewer_template_message. I haven't found any information on where exactly to request cross-wiki mass message sending, though. 

and, to be more comprehensive, also the most watched of the pages under the top category https://www.wikidata.org/wiki/Q7451504 in the other languages.

I'll skip that for now, too much work :-)

At some point we might want to start logging how many images without an information template and/or a license template have been accessed, and use that + template interwikis to identify what's missing.
