The code to call the recaptcha module is all in
/opt/zendto/www/{download.php,pickup.php,req.php,verify.php} and
it's fairly obvious code when you take a look at it. It basically
just does this:<br>
<br>
$reCaptchaPrivateKey =
$theDropbox->recaptchaPrivateKey();<br>
if ($reCaptchaPrivateKey != 'disabled') {<br>
$resp = recaptcha_check_answer ($reCaptchaPrivateKey,<br>
$_SERVER["REMOTE_ADDR"],<br>
$_POST["recaptcha_challenge_field"],<br>
$_POST["recaptcha_response_field"]);<br>
}<br>
<br>
if (($reCaptchaPrivateKey == 'disabled' ||
$resp->is_valid) .......<br>
<br>
So you just need to replace that with the code to call any CAPTCHA
of your choice. Put the PHP code for your choice of captcha module
into recaptchalib.php</blockquote>
The "AreYouAHuman.com" captcha seems to be the best of the
alternatives I have seen, as it has an accessible interface in the
form of the audio option.<br>
<br>
I've already implemented it on my development site, and may well add
it as an option to the Google reCAPTCHA one.<br>
At the moment it's a bit of a hack, but I can tidy it up and offer
it as a proper alternative.<br>
<br>
Cheers,<br>
