XF 1.2 [Modest] Repeating Header not Working

[TaylorTDHouse]

Hey All,
After a recent mishap our whole website folder was deleted, and i'm stuck having to redo all the customizations, one of them being a repeating image underneath the navigation bar. (yes, it's my bad for not exporting the finished custom style)

#modestHeader
{
    background-image:url('http://i.imgur.com/JX8URYV.png');
    background-repeat:repeat-x;
}

That's the code I am using now, but no images are showing up underneath it now. Before the mishap the image would span below the nav bar.

P.S. I actually have the image on the server, but for this i'm hosting it on imgur to prevent other variables.

That is just the CSS for the image.
Have you also edited the template to apply it?

I have not. I don't remember doing that last time, but how would I go about doing it?
