Oooh.  It must be that there's no mechanism for the browser to send
the cookie (which contains the session ID) when it requests an
image.  Sorry I caused you so much trouble.

I think what may work is to send the session ID in the URL.  That is,
construct the image URL like this:

  $url = 'captcha2.php?' . session_name() . '=' . session_id();

and then your form requests the image with:

  <img src='<?php echo $url ?>'>

or whatever the equivalent is with Smarty.

I have not tried this, it's just my best guess from reading the docs.
