That is not working… Here is what I have now and now I’m not getting any results back.
<div>
<?php
$attachment_id = get_field('field_name');
$size = "custom-size"; // (thumbnail, medium, large, full or custom size)
$image = wp_get_attachment_image_src( $attachment_id, $size );
// url = $image[0];
// width = $image[1];
// height = $image[2];
?>
<a href="<?php the_permalink() ?>" title="<?php printf(__('%s','rys'), get_the_title()) ?>" rel="bookmark" >
<img class="image-class" alt="" src="<?php echo $image[0]; ?>" />
</a>
</div>
