php_gd2.dll

which comes with PHP, on Linux, you have to re-compile PHP using the

--with-gd

option. You will also have to have at least libpng installed on your system to generate PNG files.

include_once

path to match your actual path. In this case,

$_SERVER['DOCUMENT_ROOT']

is incorrect and appears it cannot be used, or the path you have appended to it is incorrect. Your host may be able to help with the correct path.

“Message: include_once(/var/www/http://205.186.144.160/chauka/securimage/securimage.php): failed to open stream: No such file or directory”

Please guide me thank you.

Thanks for your reply… indeed the session.gc_maxlifetime was set to the default value (1440 seconds / 24 minutes). 

I updated my code to make the session lifetime longer – in a .htaccess at the root of my folder : 
{code}
php_value  session.gc_maxlifetime 10800
{code}

And I also updated the files securimage_show.php / securimage_play.php by adding 
{code}
// How long in seconds a captcha remains valid, after this time it will not be accepted
$img->expiry_time   = 10800;
{code}
after
{code}
$img = new Securimage();
{code}

So far it works as expected ! 

Thanks a lot,

This is probably due to a PHP configuration. Since the codes are stored in a PHP session by default, your session data may be getting garbage collected long before the 3 hours is up. See the session.gc_maxlifetime PHP setting.

By default PHP will potentially delete all session data older than 24 minutes if it hasn’t been touched in that long. The client may still have the session cookie, but the server has deleted the data so the cookie is no longer valid. Editing this value in php.ini or by other methods is a solution, or set your expiry_time to match PHP’s session.gc_maxlifetime value.

I’m using the latest Securimage 3.2RC2. It works great and I want to congratulate and thank you for this captcha. 

I had a question… I set the the expiration time of the captcha to 3 hours 
{code}
$img->expiry_time   = 10800;
{code}

But the captcha is always invalidated before this time. 

Does anybody here have experienced this or managed to deal with it ?

Is it related to Securimage or to PHP configuration ?

Thanks for your help,
