First create global variables (in functions.php or as a mu-plugin):

<?php

/*
 * CUSTOM GLOBAL VARIABLES
 */
function wtnerd_global_vars() {

quawn

<?php

$attachments = get_children( array('post_parent' => get_the_ID(), 'post_type' => 'attachment', 'post_mime_type' => 'image') );

if ( $attachments ) {

 // do conditional stuff here 

}
