I'm trying it now, I'm just struggling on finding the correct path
(I'm sure it's not hard at all, I've just never used code formats, paths, etc. so I have no idea what I'm doing.)
Okay, so I copied and pasted in the bit of code at the top of the post, and replaced the "urimage.png" with the name of my current background image, but what do I replace the "url" with?
I apologize for asking this, but where would you put that code? (I'm very new to Xenforo and completely lost) If you could just quickly write down where I would put that, or give me a link to a tutorial, that'd be amazing.
