$list = "pic";

require dirname(__FILE__).'/includes/header.php';

$p =& new xmlParser();
$p->parse('../' . $folder . '/fotos.xml');
$pictures = isset($p->output[0]['child']) ? $p->output[0]['child'] : array();

?>

	}
	echo $pics_html;
}

function print_pic_vars($pics){
	$count = 1;
	foreach ($pics as $pic){
		echo("var pic_$count = \"" . $pic['attrs']['LOCATION'] . "\";\r\n");
	    //echo("var pic_chicas_$count = \"" . $pic['attrs']['CHICA'] . "\";\r\n");
