The core code is just this one: make a div with the class "fluid" (obviously you can change it) to wrap the image. The div and the class are just an easy way to select that single image. If you can use another CSS selector you don'y have to use the div. With that code, the image should take all available (width) space up to the max-width you set. In the wiki code don't set a dimension for the image. In my case I set a dimension in the wikicode, so that will be its upper limit. The article shows other example as well.
