User:AoV2/fix image links

This script reverts any over-ridden (or nullified) image links back to the original state, causing each image to link to its own description page without exception. ―AoV² 08:51, 1 March 2010 (UTC)

function fix_image_links() {
	//to-do: properly discern which parts of image-page to ignore
	if(wgNamespaceNumber == 6) return; 
	
	img = document.getElementsByTagName("img");

		pn = img[i].parentNode;
		// if we have no “a” element of which to change the href, create one now
