Problem

When using %PAGE% in a link field ina mediawiki image (to link the image to another page) it does not work if the page name has a space in it. e.g. IN the example below, all references to %PAGE% work perfectly if the page name is one word, but if it is a two word page title, the link=http://mysite.com/index.php?title=%PAGE% fails - instead it links to the image file path. But this works fine if the page title is one word
