Adding a Logo in Header

I have this particular code :

<!– start Blogname/Logo –>
<div id=”blogname”>
” href=”<?php echo get_option(‘home’); ?>/”><?php echo bloginfo(‘name’); ?>
<div class=”clearer”></div>
</div>
<!– end Blogname.Logo –>

where would I add the logo in ? I don’t see the usual code of :

#header {
background #39393A no-repeat right url(images/nameofyourimage.gif);
height: 95px;
}
