Try adding <code>error_reporting(E_ALL); ini_set('display_errors', 1);</code> in securimage_show.php just after the <?php tag and open securimage_show.php directly in your browser and see if any errors are output.

Was your session save handler set in php.ini or in one of your scripts? If it was set in a script, you will need to modify securimage_show.php so it knows to use the correct session handler.

Unfortunately I don't have the modifications anymore but if you need help feel free to contact me with the contact form and show me what you have. Here is a a <a href="http://extensions.joomla.org/extensions/access-a-security/site-security/captcha/8070" rel="nofollow">Joomla extension</a> that uses securimage so you may be able to figure something out from that too.

Then securimage should work within your custom session.

The actual cause is that your user does not have permission to write to C:\inetpub\conf\temp\ where sessions are stored. That folder should either be writable by everyone or changed to something your user can write to. One thing you could do is to modify securimage.php and add <code>ini_set('session.save_path', 'C:/some_folder');</code> where C:/some_folder is a location you have permission to write to. It could be a folder in your directory that is not accessible from the web. Hi,

The only difference is I have to give the session a particular name. Why is there a problem between Securimage and a named session ?
