Captcha Help please? [closed]

[hund]

I got this simple captcha script from online. I like it, and I edited it to suit my site, but was wondering if someone could edit it to add some random lines on the captcha itself as it is somewhat too simple.I did find tutorials on how to do it but it was not working for me in.Here is the simple captcha script; I would love to modify it to have some random lines appear on the captcha.\[code\] $width = 150; $height = 24; $length = 5; $font = 'caviardreams.ttf'; $font_size = 14; $bg_color = array(245, 245, 245); $chars = 'ABCDEFGHKMNPQRSTUVWXYZ23456789'; session_start(); //putenv('GDFONTPATH=' . realpath('.')); $img = imagecreatetruecolor($width, $height); $bkgr = imagecolorallocate($img, $bg_color[0], $bg_color[1], $bg_color[2]); imagefilledrectangle($img, 0, 0, $width, $height, $bkgr); $code = ''; for($i = 0; $i < $length; $i++) { $code .= $chr = $chars[mt_rand(0, strlen($chars)-1)]; $r = rand(0, 192); $g = rand(0, 192); $b = rand(0, 192); $color = imagecolorallocate($img, $r, $g, $b); $rotation = rand(-35, 35); $x = 5+$i*(4/3*$font_size+2); $y = rand(4/3*$font_size, $height-(4/3*$font_size)/2); imagettftext($img, $font_size, $rotation, $x, $y, $color, $font, $chr); } $_SESSION['random_txt'] = md5($code); header("Content-type: image/png"); header("Expires: Mon, 01 Jul 1998 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); imagepng($img); imagedestroy($img);\[/code\]
