   Hi guys!
   I'm trying to modify the Autofocus template, actually I quite stripped it down a bit =)
   I would like to modify the home page retrieving a random image from each post instead of the last one.

   function random_image_url($size=large) {
   
   	global $post;
   	if ( $images = get_children(array(
   		'post_parent' => get_the_ID(),
   		'post_type' => 'attachment',
   		'numberposts' => 1,
   		'orderby' => 'rand()',
   		'post_mime_type' => 'image',)))
   	{
   		foreach( $images as $image ) {
   			$attachmenturl=wp_get_attachment_image_src($image->ID, $size);
   			$attachmenturl=$attachmenturl[0];
   			echo ''.$attachmenturl.'';
   		}
   
   	}  else {
   		echo '' . get_bloginfo ( 'stylesheet_directory' ) . '/img/no-attachment.gif';
   	}
   }

   that is the stripped down version of post_image_url with a different name (in case I mess it up :P).
   I tried to add orderby=rand but to the get_children function, but doesn't work, any idea?
   Cheers!

   Ok solved, I just missed the option to switch get_children with get_posts!! what a dumb!
   Here is the working code if anybody needs a random image ;)
   
   function random_image_url($size=large) {
   
   	global $post;
   	if ( $images = get_posts(array(
   		'post_parent' => get_the_ID(),
   		'post_type' => 'attachment',
   		'numberposts' => 1,
   		'orderby' => 'rand',
   		'post_mime_type' => 'image',)))
   	{
   		foreach( $images as $image ) {
   			$attachmenturl=wp_get_attachment_image_src($image->ID, $size);
   			$attachmenturl=$attachmenturl[0];
   			echo ''.$attachmenturl.'';
   		}
   
   	}  else {
   		echo '' . get_bloginfo ( 'stylesheet_directory' ) . '/img/no-attachment.gif';
   	}
   }
