full code below:

<div class="ps-contentwrapper">                 <?php if (have_posts()) : while (have_posts()) : the_post(); ?>                     <div class="ps-content">                         <h2><?php the_title(); ?></h2>                                               <p><?php echo get_the_excerpt(); ?></p>                                  </div>                         <?php endwhile; ?>                       <?php endif; ?>                          </div><!--end of contentwrapper-->             <!--image sliders-->             <div class="ps-slidewrapper">                 <div class="ps-slides">                     <?php                         $url = wp_get_attachment_url( get_post_thumbnail_id($post->id) );                     ?>                     <div style="background-image: url(<?php echo $url; ?>);"></div>                 </div><!--end of ps-slides-->                 <nav>                      <?php                         $prev_post = get_previous_post();                          $id = $prev_post->id ;                         $permalink = get_permalink( $id );                         $prev_url = wp_get_attachment_url( get_post_thumbnail_id($id) );                         ?>                             <a href="#" class="ps-prev" style="background-image: url(<?php echo $prev_url; ?>);"></a>                         <?php                              $next_post = get_next_post();                             $nid = $next_post->id ;                             $permalink = get_permalink($nid);                             $next_url = wp_get_attachment_url( get_post_thumbnail_id($nid) );                         ?>                         <a href="#" class="ps-next" style="background-image: url(<?php echo $next_url; ?>);"></a>                 </nav>             </div>

use code previous next post image url:

<?php     $prev_post = get_previous_post();      $id = $prev_post->id ;     $permalink = get_permalink( $id );     $prev_url = wp_get_attachment_url( get_post_thumbnail_id($id) ); ?> <a href="#" class="ps-prev" style="background-image: url(<?php echo $prev_url; ?>);"></a>  <?php      $next_post = get_next_post();     $nid = $next_post->id ;     $permalink = get_permalink($nid);     $next_url = wp_get_attachment_url( get_post_thumbnail_id($nid) ); ?> <a href="#" class="ps-next" style="background-image: url(<?php echo $next_url; ?>);"></a>
