So... you're saying the cookies are successfully deleted when using Opera or Firefox, but that IE still has the cookies? First of all, how do you know this? Have you tried looking for the cookies again on the "show.php" page after this logout page? If so, have you forced IE to refresh the page to ensure it's simply not a caching issue?

Other than that... can you show us where in your code you created these cookies? In order to unset them, you must call [man]setcookie/man with the same parameters (minus the value and expire time, of course) as when you first created them.

Thanks for your answer

about my check cookies code that it is :

$sql=mysql_query("SELECT *
FROM studio_users
WHERE party_user='".$_COOKIE['user_name']."' AND party_password='".$_COOKIE["password"]."'") or die("Error in select query Because ".mysql_error());
	$fetch=mysql_fetch_array($sql);	
if(mysql_num_rows($sql)!=1)
{ 
include("login.html");
}
else 
{ 
//show code be here
}

and about how i know how cleared on opera and firefox please check this demo:
http://www.karmelphotoshop.com/Karmel/show.php
user name: zepter2006
password: 11112006

after log in correctly in the menu bar choose log out, you will see in opera and firefox will redirect to show page and ask u again for user name and password but in IE will return to images show, even after refesh page

Thanks and Regards
