Oh, this is actually fairly easy. Firstly, you need to be an Admin to do it, because only Admin can edit the CSS on a wiki.

You upload the image you want onto the wiki, then in CSS put in this:

.WikiaRail .WikiaActivityModule { background: url(enter full image url name here) center top no-repeat; }

When you do it, you may need to refresh the page several/a few times. I find it best to refresh the CSS page once or twice before editing, then refreshing the page once or twice after you make the edit. You do this by hitting Fn+F5
