Apparently, MediaWiki is already doing it's job for images. But there's
something users should also do on their part.

"Image publishing guidelines" from google: [1] suggests as a best practice to
use "detailed, informative filenames". Failing to do that may cause google to
index the thumbnails because of their context in the article, not the filename.

It also mentions "Even if your image appears on several pages on your site,
consider creating a standalone landing page for each image". That's where image
description pages come to play.

Another actions that can be taken are using an image sitemap [2] [3] or even
preventing the indexation of thumbnails with robots.txt rules. Since thumbs are
grouped in a separate directory, this can be done easily.

MediaWiki already has a tool for generating sitemaps [4], maybe it can be
improved to generate image sitemaps as well (I don't know if it generates
them). Maybe create an enhancement bug for this one?
