Adding logo instead site description

Hello, I’ve the following code on my header.php and I’ll like to put my logo instead of site name & description, can anyone give me a hint?

<title><?php
global $page, $paged;
wp_title( ‘|’, true, ‘right’ );
bloginfo( ‘name’ );
$site_description = get_bloginfo( ‘description’, ‘display’ );
if ( $site_description && ( is_home() || is_front_page() ) ) echo ” | $site_description”;
if ( $paged >= 2 || $page >= 2 ) echo ‘ | ‘ . sprintf( __( ‘Page %s’, ‘imbalance2’ ), max( $paged, $page ) );
?></title>
