[Mod] Captcha (Visual Confirmation) for new users registration

[Ludo]

For those, like me, who can't get Captcha Plugin working, I've "extended" Abbas Ali Captcha Mod for comments to registration page, in order to prevent automatic registrations by spambots and alike.
This mod will present new users trying to register an additional required field to enter the confirmation code shown aside in the captcha image: no matching confirmation code = registration not allowed, quite simple :-)

DEMO: http://vanrokken.altervista.org/register.php

NEW FILES: 4 (only if Captcha Mod for comments is not installed)

• captcha.php
• include/captcha.class.php
• fonts/acidic.ttf
• fonts/hurryup.ttf

FILES TO EDIT: 2

• register.php
• lang/english.php

EXTRACT (only if Captcha Mod for comments is not installed)
attached zip file to your gallery root directory, as follows:

• captcha.php => / (root directory)
• captcha.class.php => /include
• acidic.ttf => /fonts
• hurryup.ttf => /fonts

OPEN

Works fine in other languages. Looks like you broke your Bulgarian language file by editing it. Restore a clean copy.
