Is there any kind of extension/addon for MediaWiki that would allow to use parser extension tags for placing an image as a page background? What I mean is for example here: [ screenshot: https://i.imgur.com/D1xuiOV.png / live site: http://borealis.net.pl/wiki/Hazardous_Environment_Combat_Unit ]. I've checked the source code and found that a special parser extension tag "<tlo>" (in English: background) is used. Unfortunately that website is almost abandoned (no contribution from admins for a long time) and I don't know where to look for the answer. Can someone here help me, please?
