This module is an alternative for the default Gallery2 captcha component.

ReCaptcha G2 module uses the reCAPTCHA API for Carnegie Mellon University.

the current v0.4 is a beta !

for more info, you can check:

• gallery2 forum
• reCaptcha wiki page on the codex

Protect your gallery for spam comment and brute force attack on your login.

• Download the module from: recaptcha.zip for G2 v0.4 20071115
• create a directory called “recaptcha” under gallery/modules/
• unzip the contents of recaptcha.zip into that directory
• Create your ReCAPTCHA key
• Activate the module on your Gallery website under “Site Admin” → “Plugins”
• Configure the module by entering in the public and private key that you obtained when you created your ReCAPTCHA key.
• If you have the “Captcha” plugin already installed and activated, deactivate it to avoid having both Captcha and ReCaptcha running at the same time.

if your gallery has multiple domain names, activate the plugins through each of them.

• v0.4, this version can manage a gallery with multiple domain name & bugs fix v0.4 20071115

an option to deactivate the reCaptcha validation on login page.

v0.4 Version 0.4 contains a couple of minor bugs which results in PHP notices filling the apache error log. The notices look like this :

[Sun Jun 01 17:04:40 2008] [error] [client 192.168.1.100] PHP Notice:  Use of undefined constant recaptcha - assumed 'recaptcha' in /var/www/html/gallery/modules/recaptcha/classes/ReCaptchaValidationPlugin.inc on line 75
[Sun Jun 01 17:04:40 2008] [error] [client 192.168.1.100] PHP Notice:  Undefined variable: error in /var/www/html/gallery/modules/recaptcha/classes/ReCaptchaValidationPlugin.inc on line 75

This is caused by an old array syntax which you can read about here : [http://us2.php.net/types.array] and an undefined “$error” array.

Here is a patch that fixes these bugs :
