Sometimes there's a need to render a Drupal field's value outside the scope of a node template. I used to achieve this with either Display Suite or CCK Blocks. As I'm about to change my workflow towards putting more theming stuff back to code (where it belongs) instead of clicking around slow and clumsy web interfaces I needed another solution.
1. Implement template_preprocess_page() in your theme's template.php
Of course you'll need to replace
MYTHEME with the name of your theme,
$stage_images with an arbitrary name of your choice and
field_stage_images with the name of the field you want to render.
