如何使用PHP从单个Drupal节点获取多个图像

Question

I have a custom content type in Drupal that allows multiple image uploads through a single field. I want to programmatically access the image URI's, apply my theme, and then get the output one by one. I can do this with a single image like so,

<?php
$image_style_name = 'my_theme';
$image_uri  = $entity->field_image['und'][0]['uri'];
$image = theme('image_style', array('style_name' => $image_style_name, 'path' => $image_uri));

$image = image_style_url($image_style_name, $image_uri); ?>

but I am unsure how to access the entire array of images.

For anyone who needs it... the full solution:

<?php
$image_style_name = 'my_theme';

foreach($entity->field_image['und'] as $key => $value){
$image_uri  = $entity->field_image['und'][$key]['uri'];
$image = theme('image_style', array('style_name' => $image_style_name, 'path' => $image_uri));
$output = image_style_url($image_style_name, $image_uri);    
echo $output;
}
?>

They should be in the $entity->field_image['und'] array so you should be able to loop over the array and theme each one with something like

foreach($entity->field_image['und'] as $image_field){
  ..etc
}
