[eluser]JP X3M[/eluser]
i did excatly that and then in my register controller i have these settings...

Code:

function  index(){
        
        // create the captcha-config
        $aCaptchaCfg = array(
            //'word'          => 'myrandomword',    //default: random()
            'length'        => 6,                         //default: 5
            'img_path'   => site_url().'captcha/',   //no default !
            'img_url'       => site_url().'captcha/',  // no default!
            'font_path'  => site_url().'system/fonts/', // default: ./system/fonts/
            'fonts'         => array('corsiva.ttf', 'TSCu_Comic.ttf'), // default: texb.ttf
            'font_size'     => 15,      // default: 18
            'img_width'  => '180',  // default: 170
            'img_height' => '60',   // default: 60
            'expiration' => 7200 // default: 7200
            );
        
        // get captcha-stuff
    $aCaptcha = create_captcha($aCaptchaCfg);
    }

then i tried print_r($aCaptchaCfg) and it outputs the array so i guess it should be okay...

next should i echo it or anything? thanks for your help!

UPDATE:

oh im so sorry i forgot to read the original catpcha plugin... i read it just now and i will try it first... thanks for your help though... ^__^
