Reply To: Featured image on single post as div background.

[Nick]

Thank you Tom, that did the trick.

At first the code snippet you provided didn’t exactly work. With the help of the link you provided, I was able to get it working.

I replaced
background-image: url( $thumb );
with

background-image: url('<?php echo $thumb['0'];?>')

and it worked perfectly.

I also added the following CSS so that the post image is hidden on the single page.

img.wp-post-image {
     display: none;
   }

Ultimately, my final code snippet looks like this:

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

if ( $thumb && is_single() ) {
    ?>
    <style type="text/css">
        div.page-header-image-single {
            background-image: url('<?php echo $thumb['0'];?> ');
            background-attachment: fixed;
            background-repeat: no-repeat;
            background-position: top;
	    width: 100%;
	    height: 300px;
            margin: 0px;
        }
        img.wp-post-image {
            display: none;
        }
    </style>
    <?php
}
?>

Thank you again for your help. The add-on made it very easy.
