You can always try this :
h1.Header-title a {
text-indent: -1000000px; /* We dont want you anymore, filthy text */
overflow: hidden;
display: block;
width: ; /* your image width */
height: ; /* image height */
background: url(/*path/to/my/img.png */) no-repeat;
margin-top: 10px; /* adjust to your liking */
}
All of this is intended to be put on your custom CSS box via your admin panel.
