Simple Image Fix?

Here is the code for the main template

<?php get_header(); ?>

<div id=”content” class=”narrowcolumn”>

<h2 class=”center”>Welcome Online Gamers!</h2>
What is the simplest way to put an image right above where the content starts? It will be the same size as the width of template so i figured just a simple call to it would plop it above everything else on the page. What would this simple code be?
