    You could use the default wordpress function get_post_meta(). See an example from the WordPress official documentation:

    <?php if ( get_post_meta( get_the_ID(), 'thumb', true ) ) : ?>
    <a href="<?php the_permalink() ?>" rel="bookmark">
        <img class="thumb" src="<?php echo get_post_meta( get_the_ID(), 'thumb', true ); ?>" alt="<?php the_title(); ?>" />
    </a>
<?php endif; ?>
