<?php <br><br>
//Put this in functions.php <br><br>
function get_primary_image($id, $size){ <br>
$featured = wp_get_attachment_image_src( get_post_thumbnail_id($id), $size, false); <br>
if($featured){ <br>
$childURL = $featured['0']; <br>

$childURL = get_bloginfo('template_url')."/images/default.png"; <br>
} <br>
} <br>
return($childURL); <br>
} <br><br><br>
//Run this in the loop (or any place you'd like - as long as you have an ID to feed it..) <br>
//First argument is the ID.. <br>
//Second argument is the size.. It'll handle 'large', 'medium', 'thumbnail' or even <br><br>
'array(100, 100)'.. <br>
get_primary_image(get_the_ID(), 'large'); <br><br>
