I don't -want- to upload images, this particular images is in wiki/skins/common/images/mediawiki.png - the message is just what jou get when you click on the text. When I enter http://url/to/wiki/skins/common/images/mediawiki.png in my browser I I get to see the image just fine.
That's not part of the in-wiki universe and so can't be referenced via [[Image:Mediawiki.png]].
If for some reason you want to use it in the wiki, either enable uploads and upload it, or enable image URL references (possibly insecure and prone to abuse) and use the full URL.
