Thread:Project:Support desk/Vector Skin: Adding background to all areas of wiki

Hey all. I have googled, and read and have been unable to find anything. I've been trying to find a way to add a background image to all sections of the wiki; the sidebar, top, bottom and central content area. I cannot find anything that is pointing me in the right direction.

I am using the Vector skin and I've made a couple of adjustments to it (mostly width of the sidebar and changes to fonts), version 1.22.6 of Mediawiki.

Any help would be appreciated.
