Drupal 7 load an image from a field

gistfile1.txt

<?php

$image = field_get_items('node', $node, 'my_field_name')) {

// current is just a quick way to get the first item in the array - you would probably array_pop here or just call
// $image = $image[0];
$image = current($image);
$image_uri = $image['uri'];

// Run the image through image styles.
$image = image_style_path('profile-small', $image_uri);
