Hi I’m using some code to create a slideshow with lytebox functionality – the following code is used in the loop to pull each image attached to a post in sequence.

It seems to be only pulling the large image, even thought I’ve set the value to medium – any ideas how I can get .wp_get_attachment_url($attachment->ID, ‘medium’, false, false) to be pulling the medium sized images?

thanks

                                <?php
$argsThumb = array(
'order'          => 'DESC',
'post_type'      => 'attachment',
'post_parent'    => $post->ID,
'post_mime_type' => 'image',
'post_status'    => null
);
$attachments = get_posts($argsThumb);
if ($attachments) {
foreach ($attachments as $attachment) {
echo '<div class="images"><a class="lytebox" href="' .wp_get_attachment_url($attachment->ID, 'medium', false, false). '"><img src="'.wp_get_attachment_url($attachment->ID, 'medium', false, false).'" /><div class="caption">'.apply_filters('the_content', $attachment->post_content).'</div></a></div>';
}

}
