<?php query_posts('category_name=sure-service&showposts=2');
							if ( have_posts() ) : while ( have_posts() ) : the_post();
							?>
								<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
								<div class="est_text">
								<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' ); ?>
								<? if(has_post_thumbnail()) { ?>
									<img src="<?php echo $image[0]; ?>" alt="" width="76" height="76"/>
									<? } else { ?>
										&nbsp;
									<? } ?>
