 * Hi,
 * I’m creating previous and next buttons for each single blog post. So I have returned
   the thumbnails for each previous and next post.
 * The issue is I want to hard crop the thumbnails returned to a specific size due
   to some featured images being portrait vs landscape.
 * 1st version of my code:
 *     ```
       $prevPost = get_previous_post('true');
       $prevthumbnail = get_the_post_thumbnail($prevPost->ID, array(300,300, true));
       ```
   
 * The portrait thumbnail image assigned to one of the posts is being resized but
   only on one edge. It’s not turning into a 300×300 square with a hard crop.
 * Can this crop be made here? or does it have to happen when the thumbnail is added
   to the post (via adding a new image size)?

 * UPDATE
 * It looks as though you can’t crop on the fly (or at least I couldn’t make this
   work).
 * So my code in my functions.php file is as follows:
 *     ```
       add_theme_support( 'post-thumbnails' )//this adds thumbnail support;
       add_image_size( 'prevnextimage', 400, 300, true );//this adds a new image size
       ```
   
 * In my single.php file the code is as follows:
 *     ```
       <?php $prevPost = get_previous_post('true');
       $prevthumbnail = get_the_post_thumbnail($prevPost->ID, 'prevnextimage'); ?>
       ```
   
 * I had to then use the regenerate thumbnail plugin here: [https://wordpress.org/plugins/regenerate-thumbnails/](https://wordpress.org/plugins/regenerate-thumbnails/)
