Add that in style sheet. I use Notepad++ for all my coding needs.

You need to check out where you want the background i.e. the background of which DIV and then you can add this into style sheet :

#DIV_WHERE_YOU_WANT_BG {

background-image:url('img.gif');

}

and the path to the image is relative to the file. make sure it is correct too.
