Something like this might help: http://wordpress.stackexchange.com/questions/115954/featured-image-as-background-image-on-pages

So you could write some CSS in the wp_head hook in GP Hooks like this:

<?php 
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id( get_the_ID() ), 'full' );

if ( $thumb && is_single() ) {
    ?>
    <style>
        .whatever-element {
            background-image: url( $thumb );
        }
    </style>
    <?php
}
?>

Make sure you check the “Execute PHP” checkbox.
