Featured Image Link to next post?

Question

Hello i wonder if anyone knows this is possible?

A post featured image click to view next post...?

For example..

<a href="next-post">
 <?php the_post_thumbnail('post-thumbnails'); ?>
</a>

I assume its something from the WordPress pagination, as when it gets to the final post/image it needs to go back to the first one.

Any idea if it can be done?

Something like this should work for your single.php template:

<?php
$next_post = get_adjacent_post( false,'',false );
if( isset($next_post->ID) ):
    $next_id = $next_post->ID;
else:
    $next_post = new WP_Query( 'posts_per_page=1&post_type=photo&order=ASC' );
    $next_id = $next_post->post->ID;
endif;
?>
    <a href="<?php echo get_permalink( $next_id ); ?>">
        <?php echo get_the_post_thumbnail( $next_id, 'thumbnail' ); ?>
    </a>
