salva raga, premetto che di php non conosco molto, ma ne ho bisogno per un sito che sto facendo con degli amici! quindi:
io ho:
il file php del captcha:

  4.  * Project:     Securimage: A PHP class for creating and managing form CAPTCHA images<br />
  5.  * File:        form.php<br /><br />
  6.  *
  7.  * This is a very simple form sending a username and password.<br />
  8.  * It demonstrates how you can integrate the image script into your code.<br />
  9.  * By creating a new instance of the class and passing the user entered code as the only parameter, you can then immediately call $obj->checkCode() which will return true if the code is correct, or false otherwise.<br />

Il computer non è una macchina inteligente nelle mani di gente stupida; ma è una macchina stupida nelle mani di gente intelligente (o almeno si spera).
