Hi

i m using following code for displaying captcha image--

<?php
session_start();
$PHP_SELF = $_SERVER['PHP_SELF'];
$errore = 0;
if(isset($_POST['submit']) && isset($_SESSION['captcha'])) {
if(isset($_POST['code'])){
	$_code = $_POST['code'];
	if($_SESSION['captcha'] == $_code){
		header("Location: contact2.php");
		exit;
	} else {
		$errore = 1;
	}
} else {
	$errore = 1;
}
}
if(!isset($_SESSION['captcha'])){session_register('captcha');}
$PHP_SELF = $_SERVER['PHP_SELF'];
$stringa = '';
$cifre = 5;
for($i=1;$i<=$cifre;$i++){
$letteraOnumero = rand(1,2);
if($letteraOnumero == 1){
	// lettera
	$lettere = 'ABEFHKMNRVWX';
	$x = rand(1,11);
	$lettera = substr($lettere,$x,1);
	$stringa .= $lettera;
} else {
	$numero = rand(3,7);
	$stringa .= $numero;
}
}
$_SESSION['captcha'] = $stringa;
?>
