    I've modify the gallery shortcode to do a better and a cleaner job

    here's the code
    wp-includes/media.php line 384

    function gallery_shortcode($attr) {
    	global $post;
    
    	// Allow plugins/themes to override the default gallery template.
    	$output = apply_filters('post_gallery', '', $attr);
    	if ( $output != '' )
    		return $output;
    
    	// We're trusting author input, so let's at least make sure it looks like a valid orderby statement
    	if ( isset( $attr['orderby'] ) ) {
    		$attr['orderby'] = sanitize_sql_orderby( $attr['orderby'] );
    		if ( !$attr['orderby'] )
    			unset( $attr['orderby'] );
    	}
    
    	extract(shortcode_atts(array(
    		'order'      => 'ASC',
    		'orderby'    => 'menu_order ID',
    		'id'         => $post->ID,
    		'itemtag'    => '',
    		'icontag'    => '',
    		'captiontag' => '',
    		'columns'    => 4,
    		'size'       => 'thumbnail',
    	), $attr));
    
    	$id = intval($id);
    	$attachments = get_children( array('post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
    
    	if ( empty($attachments) )
    		return '';
    
    	if ( is_feed() ) {
    		$output = "\n";
    		foreach ( $attachments as $id => $attachment )
    			$output .= wp_get_attachment_link($id, $size, true) . "\n";
    		return $output;
    	}
    
    	$listtag = tag_escape($listtag);
    	$itemtag = tag_escape($itemtag);
    	$captiontag = tag_escape($captiontag);
    	$columns = intval($columns);
    	$itemwidth = $columns > 0 ? floor(100/$columns) : 100;
    
    	foreach ( $attachments as $id => $attachment ) {
    		$link = wp_get_attachment_image($id, $size, true);
    		$output .= '<a href="'.wp_get_attachment_url($id).'">'.$link.'</a>';
    	}
    
    	$output .= "<br style='clear: both;' />";
    
    	return $output;
    }
