New line in long strings, dynamically printed on an image

[JinF]

Hey,

I made myself a randomized quote selector for a signature script, but some of the quotes I am using are rather long and run off the image. I tried using \r\n inside the strings to make em go over to the next line, but that only comes up as weird symbols on the image.

<?php 

$image = "signature.png"; 
$im = imagecreatefrompng($image); 
$white = ImageColorAllocate ($im, 255, 255, 255); 


$usedquote = rand(0,13);

$quote[0] = "Quote";
$quote[1] = "Quote";
$quote[2] = "Quote";
$quote[3] = "Quote";
$quote[4] = "Quote";
$quote[5] = "Quote";
$quote[6] = "Quote";
$quote[7] = "Quote";
$quote[8] = "Long\r\n quote";
$quote[9] = "Long\r\n quote ";
$quote[10] = "Quote";
$quote[11] = "Very\r\n long\r\n quote";
$quote[12] = "Very\r\n long\r\n quote";
$quote[13] = "You get the idea";




ImageString($im, 3, 100, 0, "$quote[$usedquote]", $white); 
header("Content-Type: image/png"); 
Imagepng($im,'',100); 
ImageDestroy ($im); 
?>  

Result can be seen here .

What can I do to split the long quotes to appear on two lines or more so the whole thing shows?

function ImageStringWrap($image, $font, $x, $y, $text, $color, $maxwidth)
{
   $fontwidth = ImageFontWidth($font);
   $fontheight = ImageFontHeight($font);

   if ($maxwidth != NULL) {
       $maxcharsperline = floor($maxwidth / $fontwidth);
       $text = wordwrap($text, $maxcharsperline, "\n", 1);
     }

   $lines = explode("\n", $text);
   while (list($numl, $line) = each($lines)) {
       ImageString($image, $font, $x, $y, $line, $color);
       $y += $fontheight;
     }
}
