<div id="body">     <!-- Body [sidebar, posts] -->           

            <div id="content">     <!-- Contents -->

            <?php
	    $post = $wp_query->post;
	   	 $id = $wpdb->get_var("SELECT term_id FROM $wpdb->terms WHERE slug='" .get_option('gallery-category') ."'");

	   	   ?>

         <?php if (have_posts()) : ?>
<?php query_posts('cat=-' .$id .''); ?>
