So, is there a plugin to be used or - otherwise - a developer which could help me out of this?
Have you looked at the FileLink-Extension?
http://www.mediawiki.org/wiki/Extension:FileLink and http://assela.pathirana.net/FileLinkExtension
It's a bit tricky, be sure to read the discussion pages as well.
Also, you need a Firefox-Extension to allow using filelinks from the browser: https://addons.mozilla.org/de/firefox/addon/281/
Good luck! Katharina
