title: ACF Gallery thumbnails (image included)
body: <p>I am trying to achieve the below image:
  <img src="https://i.stack.imgur.com/gDQ2R.jpg" alt="image with thumbnails for more images"></p>
  
  <p>Basically, I have set up ACF Gallery, and used the code below:</p>
  
  <pre><code>&lt;?php $images = get_field('gallery'); if( $images ): ?&gt; &lt;!-- This is the gallery filed slug --&gt;
    &lt;?php foreach( $images as $image ): ?&gt; &lt;!-- This is your image loop --&gt;
      &lt;img src="&lt;?php echo $image['url']; ?&gt;" alt="&lt;?php echo $image['alt']; ?&gt;" /&gt; &lt;!-- Image Code --&gt;
    &lt;?php endforeach; ?&gt; &lt;!-- This is where the image loop ends --&gt;
  &lt;?php endif; ?&gt; &lt;!-- This is where the gallery loop ends --&gt;
  </code></pre>
  
  <p>Which now lists all the images in the gallery. What I am looking for, is the first image to be full size, and the other 3 images to be thumbnails, like the image, which when clicked, change the full size image.</p>
  
  <p>Anyone have any ideas?</p>
  
  <p>EDIT:</p>
  
  <p>Im open to another way of doing this</p>
