One can improve CAPTCHA-type "CAPTCHA with varying fonts and backgrounds"
- by adding backgrounds (PNG-images, 140x40 pixels) to backgrounds/
- and by adding TrueType-fonts to fonts/


How to use:
use 
	require_once(WB_PATH.'/include/captcha/captcha.php'); // will output a table with 3 columns: |CAPTCHA|Input|Text|
and put 
	<?php call_captcha(); ?>
into your form.


The CAPTCHA-code is allways stored in $_SESSION['captcha']
The user-input is in $_POST['captcha'] (or $_GET['captcha']).


call_captcha() will output code like this
<table class="captcha_table"><tr>
  <td><img src="<?php echo WB_URL.'/include/captcha/captchas/'.CAPTCHA_TYPE.".php?t=$t"; ?>" alt="Captcha" /></td>
  <td><input type="text" name="captcha" maxlength="5" style="width:50px" /></td>
  <td class="captcha_expl"><?php echo $MOD_CAPTCHA['VERIFICATION_INFO_TEXT']; ?></td>
</tr></table>
