S2 - A Novel Conundrum image help! Options

[silentdecay]

Hey, I'm trying to add an image onto my LJ above the "Entries · Archive · Friends · Profile" links part, basically just an image to replace the "Silent · Decay" text with something which looks a little nicer.

I've tried looking for help, but I'm not really sure what I'm looking for.

I'm using S2 with the A Novel Conundrum layout. You can view my layout here - http://envindavsorg.livejournal.com/

The only code I'm using so far is this -

CODE

body{
background-color:rgb(0,0,0);
background-image:url(http://img405.imageshack.us/img405/9747/newlayoutcopy4yw.jpg);
background-position:center center;
background-repeat:repeat-y;
background-attachment:fixed;
}

If anyone can help me that'd be ace :)

- Mike
