change logo

Hi all
How to change the logo for wordpress header want to change img logo

<div id="header">
<div id="headerimg">
<h1><a href="<?php echo get_settings('home'); ?>/"><?php bloginfo('name); ?></a></h1>
<div class="description"><?php bloginfo('description'); ?></div>
<div id="search">
<?php include (TEMPLATEPATH . '/searchform.php'); ?>
</div>

 

Can anybody help me

 

Inside style.css find:

 .Header .LS { position: absolute; top: 30px; left: 30px; background: url(images/LogoIcon.png) no-repeat left top; width: 40px; height: 43px;}

Code (markup):

Replace LogoIcon.png with your logo name and upload your logo to the /images/ directory of your theme.
You should also replace 40px; height: 43px with your logo sizes.
