How to Add Featured Image to A Custom Loop

Hi everyone,

I need to edit a custom loop which is this:

<?php
  // as we need it after 1st post we need to have a counter
  $post_counter = 0;
  ?>
  <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
      <div class="cool-loop">
            <div class="date">
                <div class="background">
                    <span class="day"><?php the_time('j') ?></span><br />
                    <span class="month"><?php the_time('M') ?></span>
                </div>
            </div>
            <h2 class="title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
           <div class="post-content">
            <?php
                if(is_singular()){
                    the_content();
                } else {

                  do_action( 'ultimatum_post_content',$instance );

                      // now lets check counter
                   if($post_counter==0){
                      ?>
                      <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- Test Responsive -->
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-0375707664358081"
     data-ad-slot="5026873448"
     data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
                      <?php
                      // increase the counter
                      $post_counter++;
                  }
                }
              ?>
           </div>
        </div>
  <?php endwhile;
      ultimatum_posts_nav($instance);
  else: ?>
      <div class="no-content">
           <p>Sorry, nothing to display here.</p>
       </div>
  <?php endif; ?>

I use this code for this page: http://nulis.net/category/video-tutorial/

I need some help to customise the loop code above so that I will do:
- Delete the Date and Month shown on http://nulis.net/category/video-tutorial/
- Show featured image on the left of every post excerpt.

Thank you :slight_smile:
