In reply to siddharth. Yes, use the pool option in Captcha configuration.

// Captcha configuration
$config = array(
    'img_path'      => 'captcha_images/',
    'img_url'       => base_url().'captcha_images/',
    'img_width'     => '150',
    'img_height'    => 50,
    'word_length'   => 8,
    'pool'   => abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ,
    'font_size'     => 16
);
$captcha = create_captcha($config);

Thank you very much for this code. I was a great inspiration to implement it in my own program. It helped me how to have an Ajax refresh button on my login page.

In reply to Rajkamal. You'll find the captcha helper in system folder - /system/helpers/captcha_helper.php
