Header image

Sure. You can edit line 34 of header.php:
<h1><a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>

Place your image there using ‘img src’.

How give me me some more step. I enjoy your template but cluesless about changing it.

I found <h1>/”><?php bloginfo(‘name’); ?></h1>

now what? How do i put in the image from my desk top?
