This tutorial should allow you to change your normal title to an image using CSS.

First of all, add this to your CSS.

/* css */
h3#header {
background: url(your link here)
no-repeat top right;
width: 2329px;
height: 25px;
margin: 0 0 0 -2000px;
}

And here is HTML that you have to use:

<h3 id="header">
Your Title Here.
</h3>
