Description

Sometimes, MediaWiki returns image previews with incorrect type.
Which produces glitches in my browser.
Examples:
good, Content-Type: image/jpeg:
https://upload.wikimedia.org/wikipedia/mediawiki/thumb/a/a9/Example.jpg/150px-Example.jpg
bad, Content-Type: application/x-www-form-urlencoded:
https://upload.wikimedia.org/wikipedia/mediawiki/thumb/a/a9/Example.jpg/100px-Example.jpg
