Hola a todos tengo un pequeño error con el Captcha, es que no se como poner el código a este mismo y por esa razón no me deja mandar el comentario, porque no me se el código y necesito cambiarlo.
les mando el código:
captcha.php
<?php
session_start();
require_once('class.simplecaptcha.php');
/*
*****CONFIGURATION STARTS*****
*/
//Background Image
$config['BackgroundImage'] = "white.png";
//Background Color- HEX
$config['BackgroundColor'] = "FFFC00";
//image height - same as background image
$config['Height']=30;
//image width - same as background image
$config['Width']=100;
//text font size
$config['Font_Size']=21;
//text font style
$config['Font']="verdana.TTF";
//text angle to the left
$config['TextMinimumAngle']=15;
//text angle to the right
$config['TextMaximumAngle']=25;
//Text Color - HEX
$config['TextColor']='000000';
//Number of Captcha Code Character
$config['TextLength']=6;
//Background Image Transparency
$config['Transparency']=50;
/*
*******CONFIGURATION ENDS******
*/
//Create a new instance of the captcha
$captcha = new SimpleCaptcha($config);
//Save the code as a session dependent string
$_SESSION['string'] = $captcha->Code;
$_GET["code_captcha"] = $captcha->Code;
?>
