hi all!
i have two image files i want to upload to my wiki that are detected as zip archives though they in fact are images (which `file` says, too). now i have no idea how to teach mediawiki to identify the files correctly. i can change the metadata in the database, but that only leads to another surprise: those changes are reverted the next time the image pages are accessed. huh? where does this information come from then? why are the metadata even stored in the database when it's not authoritative?
can someone please shed some light on this matter. i'm absolutely new to running a mediawiki instance of my own. you can find the two files in question here:
