Three easy steps to add an Image code verification in your plugin.

1. Create a secure_image object.

Code: include secure_img_handler.php 
include_once(e_HANDLER.'secure_img_handler.php');
$sec_img = new secure_image;

2. Add the secure image and input field in your form.

Code: add in html 
<input type="hidden" name="rand_num" value="'.$sec_img->random_number.'" />
'.$sec_img->r_image().'<br />
<input class="tbox login verify" type="text" name="code_verify" size="15" maxlength="20" /><br />

3. In your form processing, verify if the code entered by the user is correct.

Code: verify sumited data 
if (!$sec_img->verify_code($_POST['rand_num'], $_POST['code_verify']))
{
    $error = true;
    $msg = "Sorry invalid image code.";
}
