    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';
	}
}
