Wordpress get image url (currently using wp_get_attachment_url) - image

Question

Having a little trouble in getting image attachment urls in wordpress. This is my code so far:
<?php // find images attached to this post / page.
global $post;
$thumb_ID = get_post_thumbnail_id( $post->ID );
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'numberposts' => -1,
'orderby' => 'menu_order',
'order' => 'ASC',
'exclude' => $thumb_ID,
'post_parent' => $post->ID
);
$images = get_posts($args);
?>
<?php // Loop through the images and show them
if($images)
{
foreach($images as $image)
{
echo wp_get_attachment_image_url($image->ID, $size='attached-image');
}
}
?>
Which returns nothing. If I swap out wp_get_attachment_image_url($image->ID, $size='attached-image'); for wp_get_attachment_image($image->ID, $size='attached-image'); this works fine, but brings in the image rather than just the url.

The following code will loop through all image attachments and output the src url. Note that there are two methods shown, depending on your need.
<?php
global $post;
$args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_mime_type' => 'image', 'post_status' => null, 'post_parent' => $post->ID );
$attachments = get_posts($args);
if ($attachments) {
foreach ( $attachments as $attachment ) {
// Method #1: Allows you to define the image size
$src = wp_get_attachment_image_src( $attachment->ID, "attached-image");
if ($src) {echo $src[0];}
// Method #2: Would always return the "attached-image" size
echo $attachment->guid;
}
}
?>
