Link images to post.

Hi all

I’m sure this is simple but I can’t see how to do it.

I know how to add images to a post – Click in the post, Add Media, choose thumbnail.

This gives me an thumbnail in the post.

I think what I want to do is link thumbnails to the post so I can control where the thumbnails appear on the page.

I have a template like this.

<div class="content_div">
		<?php

			$car_args = array(
				'post_type' => 'post',
				'category_name' => 'car',
				'order' => 'asc'
			);

			$cars = new WP_Query($car_args);

			if($cars->have_posts()):
				while($cars->have_posts()):
					$cars->the_post();
		?>

			<article class="service">

		      <div class="right_col">

		          <h4><?php the_title(); ?></h4>

		          <?php the_content(); ?>

		      </div><!--right_col-->

		      <aside class="side_bar">
		        <ul>

            <!-- I would like to add the thumbnails here -->

		        </ul>
		      </aside>

		  </article><!-- service-->

			<?php endwhile; endif; ?>
			<?php wp_reset_postdata(); ?>

		</div><!--content_div-->

I have posts about car’s with category name ‘car’, I’m using the category name in the WP_Query.

Some of these posts have images. If there are images with the post I would like to add them as a list in the aside.
