PHP Captcha code problem?

It was working great yesterday,.. and now. .. it isn't.. ???

<?php
session_start();
if(isset($_POST["captcha"])) {
 if(($_SESSION['captcha_code'] == $_POST['captcha']) && (!empty($_SESSION['captcha_code'])) ) {
  //Passed!
  $captcha_msg="Thank you";
 }else{
  // Not passed 8-(
  $captcha_msg="*** invalid image code, please put the right code in the box";
  if(isset($_POST["MM_insert"])){
     unset($_POST["MM_insert"]);
  }
  if(isset($_POST["MM_update"])){
   unset($_POST["MM_update"]);
  }
 }
}
class CaptchaImage {
 //var $font = realpath("verdana.ttf");
 var $font = "/home55/www/website.com/this/verdana.ttf";
 function hex_to_dec($hexcolor){
 //convert hex hex values to decimal ones
 $dec_color=array('r'=>hexdec(substr($hexcolor,0,2)),'g'=>hexdec(substr($hexcolor,2,2)),'b'=>hexdec(substr($hexcolor,4,2)));
 return $dec_color;
 }
 function generateCode($characters) {
  /* list all possible characters, similar looking characters and vowels have been removed */
  $possible = '23456789bcdfghjkmnpqrstvwxyz'; 
  $code = '';
  $i = 0;
  while ($i < $characters) { 
   $code .= substr($possible, mt_rand(0, strlen($possible)-1), 1);
   $i++;
  }
  return $code;
 }
 function CaptchaImage($width='120',$height='30',$characters='6',$hex_bg_color='FFFFFF',$hex_text_color="000000",$hex_noise_color="CC0000", $img_file='captcha.jpg') {
  $rgb_bg_color=$this->hex_to_dec($hex_bg_color);
  $rgb_text_color=$this->hex_to_dec($hex_text_color);
  $rgb_noise_color=$this->hex_to_dec($hex_noise_color);
  $code = $this->generateCode($characters);
  /* font size will be 60% of the image height */
  $font_size = $height * 0.35;
  $image = @imagecreate($width, $height) or die('Cannot Initialize new GD image stream');
  /* set the colours */
  $background_color = imagecolorallocate($image, $rgb_bg_color['r'], $rgb_bg_color['g'],$rgb_bg_color['b']);
  $text_color = imagecolorallocate($image, $rgb_text_color['r'], $rgb_text_color['g'],$rgb_text_color['b']);
  $noise_color = imagecolorallocate($image, $rgb_noise_color['r'], $rgb_noise_color['g'],$rgb_noise_color['b']);
  /* generate random dots in background */
  for( $i=0; $i<($width*$height)/3; $i++ ) {
   imagefilledellipse($image, mt_rand(0,$width), mt_rand(0,$height), 1, 1, $noise_color);
  }
  /* generate random lines in background */
  for( $i=0; $i<($width*$height)/150; $i++ ) {
   imageline($image, mt_rand(0,$width), mt_rand(0,$height), mt_rand(0,$width), mt_rand(0,$height), $noise_color);
  }
  /* create textbox and add text */
  $textbox = imagettfbbox($font_size, 0, $this->font, $code);
  $x = ($width - $textbox[4])/2;
  $y = ($height - $textbox[5])/2;
  imagettftext($image, $font_size, 0, $x, $y, $text_color, $this->font , $code);
  /* save the image */
  imagejpeg($image,$img_file);
  imagedestroy($image);
  echo "<img src=\"$img_file?".time()."\" width=\"$width\" height=\"$height\" alt=\"security code\" id=\"captchaImg\">";
  $_SESSION['captcha_code'] = $code;
 }

}
?>

And then it is getting stuck down here: What I mean by stuck, is it is loading everything ahead of this.. but stops right before this php $captcha call???

<td valign="bottom"><?php $captcha = new CaptchaImage(120,50,6,'FFFFFF','000000','99CC00');?><label><input name="captcha" type="text" class="text_calendar2" id="captcha" size="12" /> </label> 
                    <strong>&larr; INSERT CODE HERE</strong><br />
<div style="color:#CC3333; font-weight:bold; margin-left:25px; background-color:#FFFF00; margin-bottom:7px; margin-top:7px"><?php echo $captcha_msg ?></div>                  </td>

Anybody see anything odd?? Like I said, this just all of a sudden happened. Like a ghost did it. It was working fine yesterday and then today.. bang... Thanks in advance.
