Programming suggestions

Hi,

Suggestion #1

not needed to create a class with
$img = new Fox_captcha(1,1,1);

this is better:
if(Fox_captcha::test($_POST['code'])){ ...


Suggestion #2

not needed for user to set $img->class_dir

find the path automatically:

$this->class_dir = str_replace('Fox_captcha.php', '', __FILE__);
$this->class_dir = str_replace('\\', '/', $this->class_dir);
$this->class_dir = str_replace($_SERVER['DOCUMENT_ROOT'], '', $this->class_dir);
$this->class_dir = '/' . ltrim($this->class_dir, '/');

Hi,
Thank you for your valuable suggestion. I will regard them in the next version.
