active page problem

Hi.

I have a problem on my home page. I use pictures display in home page from a category name”new works”. But the active link is on the category name not the home page. Look here: https://www.kikoslanitis.com/

The code in index file is like this:

<div class="news">

                <?php query_posts('showposts=7&category_name=new works');
				  	if (have_posts()) : ?><?php while (have_posts()) : the_post();
					$image = "";
					$first_image = $wpdb->get_results(

					"SELECT guid FROM $wpdb->posts WHERE post_parent = '$post->ID' "
					."AND post_type = 'attachment' ORDER BY <code>post_date</code> ASC LIMIT 0,1"

					);

					if ($first_image) {
						$image = $first_image[0]->guid;
					}
                ?>
                	<div class="pic">
            			<a href="<?php the_permalink() ?>" rel="<? bloginfo('template_directory'); ?>/scripts/timthumb.php?src=<?php echo $image; ?>">
						<img src="<? bloginfo('template_directory'); ?>/scripts/timthumb.php?src=<?php echo $image; ?>&w=50&h=50&zc=1&q=100" /></a>
            	</div> <!-- .pic -->
				<?php endwhile; ?><?php endif; ?>

            </div>

If i remove the “&category_name=new works” is working fine but i want display images from that category only. The active class is working fine in the other pages. Also my nav bar is on the footer. Here is the code:

<ul class="page">
            	<li><a href="<?php echo get_option('home'); ?>" accesskey="1" <?php if( is_home()) : ?> class="active" <?php endif; ?> title="Back to Frontpage">Home</a></li>
			<?php
			if( is_page() ) $curpage = $post->ID;
			$pages = get_pages('sort_column=menu_order');
			foreach( $pages as $page ) {
				$this_css = '';
				$this_link = get_page_link($page->ID);
				if( $curpage == $page->ID ) $this_css = ' class="active"';
				echo "<li><a $this_css href=\"$this_link\">" . $page->post_title . "</a></li>\n\t\t";
			} ?>
            </ul>
            <div class="ffix"></div>
        </div>
        <div class="category">
        	<h2>Portfolio</h2>
            <ul class="cats">
            	<?php wp_list_categories('title_li=&orderby=ID'); ?>
            </ul>
        </div>

Anyone can help?
Thanks
