How do I get the images of child articles?

Kirby 2 Questions 🤔

I am basically using the $articles from the Standard Template

<?php foreach($articles as $article): ?>
  <div class="row">
    <div class="col-lg-6 col-md-6">
      <div class="blogpost">
        <div class="posttitle">
          <h1>
           <a href="<?= $article->url() ?>"><?= $page->title()->html() ?></a>
           <?= $article->url() ?>
          </h1>
        </div>
      
        <div class="postcontent">
<!--           <a href="wallpapers.html"><img class="img-responsive postimage" src="4.jpg"></a> -->
          <?= $article->text()->kirbytext() ?>
<!--               <?= $article->text()->kirbytext()->excerpt(500, 'words') ?>
          <a href="<?= $article->url() ?>" class="article-more">read more</a> -->
        </div>
      </div>
    </div>
  </div>
<?php endforeach ?>

But how can I access now the images that are in these articles? I don’t get it. These $articles looks like magic to me.

<?php foreach($articles as $article): ?>
  <!-- fetch the images for an individual article -->
  <?php $images = $article->images() ?>
    <?php foreach($images as $image): ?>
      <!-- do sth. here with the image -->
    <?php endforeach ?>
<?php endforeach ?>
