How to render CCK image field within page.tpl.php
file_create_url to get the path of your image:

// $nid is the id of your node
$entity = entity_load('node', array($nid));
$uriImagefromNode = $entity[$nid]-&gt;field_image_test_field['und'][0]['uri'];
$urlImagefromNode = file_create_url($uriImagefromNode);
// $urlImagefromNode variable now has the path to the image
