File not writing text to image.

[Houdini]

I have a script that should write text into a rectangle that is generated by php. Here is what I really get with the below script.
Image and the image I used to create it with First Image and below is the code that I used, but as you can see the first link that resulted from the script has nothing in the little rectangle produced by the script.

$font = realpath("cour.ttf") ;
$text ="Test text to image";
$sizes = imagettfbbox ( 8, 0, $font, $text) ;
// Set the content-type
//header("Content-type: image/png");

//So replace by default smiley
  if ($smileyimage == "")
  {
    $smileyimage = imagecreatefrompng ("smiley_normal.png") ;
    //Get size of default smiley
    $addy = getImageSize ("smiley_normal.png") ;
  }
  else
  {
    //Get size of smiley
    $addy = getImageSize ("smiley_normal.png") ;
  }

  //Minimumsize of Image for Smiley
  $w = max ($addy[0], $sizes[2]) ;
  //Create image
  $mainimage = imagecreate($w+10, $addy[1]+30);

  // allocate Colors
  $white = imagecolorallocate ($mainimage, 255, 255, 255) ;
  $black = imagecolorallocate ($mainimage, 0, 0, 0) ;
  $bg = imagecolorallocate ($mainimage, 255, 0, 255) ;

  //set wannabe-transparancy-color to background
  imagefill ($mainimage, 0, 0, $bg) ;

  //copy smiley into image
  imagecopyresized($mainimage, $smileyimage, (($w+10)-$addy[0]) / 2, 30, 0, 0, $addy[0], $addy[1], $addy[0], $addy[1]) ;

  //draw poster
  imagerectangle ($mainimage, 0, 0, $w+9, 29, $black) ;
  imagefilledrectangle ($mainimage, 1, 1, $w+8, 28, $white) ;

  //draw text
  imagettftext ($mainimage, 8, 0, ( $w - $sizes[2]+10)/2, 24, $green, $font, $text) ;

  //do the rest *g*
  imagecolortransparent($mainimage, $bg) ;
  //header("Content-Type: image/png");
  imagepng ($mainimage) ;
  imagedestroy($mainimage);

What do I need to correct ths script and actually get a message in the rectangle (sign)?

Here is the JavaScript that is supposed to get the text variable

 $gen_simple_header = 1;
  $page_title = $lang['Smilie_creator'];
 // include($phpbb_root_path . 'includes/page_header.'.$phpEx);

  $smileydir = opendir ("./smileygenerator") ;
  $i == 0 ;
  ?>
<script language="javascript" type="text/javascript">
<!--
function emoticon(text) {
        text = '[smiley poster=' + text + ']' + document.forms['eingabeform'].eingabe.value + '[/smiley] ';
        if (opener.document.forms['post'].message.createTextRange && opener.document.forms['post'].message.caretPos) {
                var caretPos = opener.document.forms['post'].message.caretPos;
                caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text + ' ' : text;
                opener.document.forms['post'].message.focus();
        } else {
        opener.document.forms['post'].message.value  += text;
        opener.document.forms['post'].message.focus();
        window.close() ;
        }
}
