 get_post_thumbnail_id returns string, which sometimes irritates me. I know
 that it actually returns get_post_meta, which returns string, but why
 don't cast it to int or wrap it in absint.
 {{{#!php
 <?php
 function get_post_thumbnail_id( $post = null ) {
     $post = get_post( $post );
     if ( ! $post ) {
           return '';
     }
     return absint( get_post_meta( $post->ID, '_thumbnail_id', true ) );
 }
 }}}
