Thank you!
This was the solution i’ve come up with now:
$image1 = get_field('profilbild', $user);
$image2 = get_field('funbild', $user);
$name = get_field('nickname', $user);
echo '<li><div class="image_wrapper"><img class="profile1" src="';
echo $image1['url'];
echo '"/></div><img class="profile2 hoverShow" src="';
echo $image2['url'];
echo '"/><div class="imageOverlay"><p>';
echo "$name";
echo '</p></div></li>';
Maybe this helps anyone reading this later 😉
