Ralph,
That's what I did on first.php code I wonder why.
-- first.php --
session_start();
session_register('new_string');
Header("Content-Type: image/png");
$new_string;
$im = ImageCreate(200, 50);
$white = ImageColorAllocate($im, 255, 255, 255);
$black = ImageColorAllocate($im, 0, 0, 0);
srand((double)microtime()*1000000);
$string = md5(rand(0,9999));
$new_string = substr($string, 17, 5);
ImageFill($im, 0, 0, $black);
ImageString($im, 4, 96, 19, $new_string, $white);
ImagePNG($im, "verify.png");
ImageDestroy($im);
-- end // first.php --

Thank you,
Louie

You should register session for 'new_string' after assigning a value to it.
So try placing
session_start();
session_register('new_string');
after the rest of your first.php code.
That should work.

Subject: [PHP] Image verification problem..
Im trying the image verification thing I think everything goes well for the
generation of the image but when it comes to verifying the text when I typed
in any text it just generates and process the form, but when I leave it
blank it says the error. I think the session variables for $new_string is
not being passed I tried to echo the session variable but it doesn't show
up.
Any ideas on this?
I think this is the problem? elseif ($new_string == $verify_random) but I
don't think so..
