A fix for cutting down the number of queries done by the ACF

acf-repeater-query.php

<?php
  // Assuming we have ACF.
  $rows = get_field('images');
  
  // Regular ACF query with 10 images in repeater yeilds 34 queries
  foreach ($rows as $row) :
    $image_id = $row['image'];
    $image = wp_get_attachment_image_src($image_id, 'your-custom-image-size');
    echo '<img src="'. $image[0] . '" width="'. $image[1] . '" height="'. $image[2] . '" />';
  endforeach;

  // Caching the image will give only 16 queries
  foreach ( $rows as $row ) {
     $ids[] = $row['image'];
  }

  $cache = get_posts(array('post_type' => 'attachment', 'numberposts' => 5000, ));

  foreach ( $cache as $image ):
    $image_id = $image->ID;
      if ( ! in_array( $image_id, $ids, true ) ) {
          continue;
      }
      $image_src = wp_get_attachment_image_src( $image_id, 'your-custom-image-size' );
      echo '<img src="' . $image_src[0] .'" width="' . $image_src[1] .'" height="' . $image_src[2] .'" />';
  endforeach;
