While loop wordpress help

[davelearning]

Hi all,

 

I have the following which displays my posts on a wordpress blog

<?php 
		$x = 0;
		while (have_posts()) : the_post(); update_post_caches($posts); 
		$x++;
		?>
			<li<?php if ($x % 2) { } else { echo ' class="right_col"';} ?>>
				<?php unset($img); 
					if ( current_theme_supports( 'post-thumbnails' ) && has_post_thumbnail() ) {
					$thumbURL = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), '' );
					$img = $thumbURL[0];  }
					else { 
						unset($img);
						if ($wpzoom_cf_use == 'Yes')  { $img = get_post_meta($post->ID, $wpzoom_cf_photo, true); }
					else {  
						if (!$img)  {  $img = catch_that_image($post->ID);  } }
					}
					if ($img) { $img = wpzoom_wpmu($img); ?>
					<a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php bloginfo('template_directory'); ?>/scripts/timthumb.php?src=<?php echo $img ?>&w=75&h=75&zc=1" alt="<?php the_title(); ?>" /></a><?php } ?>
				<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a><span class="comm_bubble"><?php comments_popup_link('0', '1', '%', ' ', ' '); ?></span>
				<span class="meta"><?php the_time("$dateformat $timeformat"); ?> <?php edit_post_link( __('Edit', 'wpzoom'), ' ', ''); ?></span>
				<?php wpe_excerpt('excerpt_tabs', 'wpe_excerptmore'); ?>

			</li><?php endwhile; ?>

		</ul><?php endif; ?>

 

What I would like to do is limit the max posts to 6, but I cant seem to work out a way of doing it!

 

Any pointers?

 

Cheers
