Hi there,

The top part of this reply is mainly about arrays so hopefully if you ever find yourself in a similar situation in the future you can hopefully avoid soiling your office chair – teach a man to fish and all that.
If you want to just get the code skip to the bottom.

You can think of an array as a collection of information (AKA values). You can get a specific value from an array by using a key.

$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

echo $array['foo']; //will echo bar

In php the key is optional, when it is not used PHP will use the increment of the largest previously used integer key.

$array = array("foo", "bar", "hello", "world");
var_dump($array);

Outputs:

array(4) {
  [0]=>
  string(3) "foo"
  [1]=>
  string(3) "bar"
  [2]=>
  string(5) "hello"
  [3]=>
  string(5) "world"
}

The documentation for wp_get_attachment_image_src in the codex tells us that it returns an array containing:

• [0] => url
• [1] => width
• [2] => height

So the solution to your problem should be:

<?php foreach( $images as $image ) : ?>
$full_image = wp_get_attachment_image_src(,$image->ID,'full');
$medium_image = wp_get_attachment_image_src(,$image->ID,'medium');
<a class="zoom" rel="thumbnails" href="<?php echo $full_image[0]; ?>"><img src="<?php echo $medium_image[0]; ?>"></a>
<?php endforeach; ?>
