Display an image based on field value

How about this?

<?php $meta = get_post_meta( get_the_ID(), 'region', true );
    if ($meta == 'NA') { ?>
        <img src="https://www.esrnetwork.com/wp-content/uploads/2016/12/NA.png" width="25" height="25"/>
    <?php } elseif ($meta == 'EU') { ?>
        <img src="https://www.esrnetwork.com/wp-content/uploads/2016/12/EU.png" width="25" height="25"/>
  <?php } else {
        } ?>
