Render a field

I am experimenting with this module and can't seem to render a field.

I've tried using the following snippets, without success

hide($content['field_collection_images']);
$result = render($content['field_collection_images']); 
return $result;

And

field_get_items('node', $node, $field_collection_images);
$result = $node->field_collection_images[$node->language][0]['value']
return $result;
