Make CIP images for Cisco IP phones in PHP

I found several scripts to create CIP files in the web but none of them really worked 100%. This script is a modified version of a script I found at PHP.net. It SHOULD work 100%. It’s meant as an include file and it provides 2 functions.
makecipfromfile(filename:string) - creates a CIP image from a file
makecipfromressource(ressource:imageressource) - creates a CIP image from a PHP image ressource
The functions both return all image-relevant tags (
Example use:
<?php
include "makecip.php";
header("Content-type: text/xml; charset=iso-8859-1");
header("Connection: Keep-Alive");
header("Cache-Control: private");
?>
<CiscoIPPhoneImage>
<Title>bla</Title>
<LocationX>0</LocationX>
<LocationY>0</LocationY>
<?php print makecipfromfile("image.gif"); ?>
</CiscoIPPhoneImage>
Here is the script now:
<?php
function makecipfromfile($IMAGESOURCE) {
//Sets the max width and height for the image
$MAXWIDTH = 133;
$MAXHEIGHT = 65;
//Sets the display location on the phone
$LOCATIONX = -1;
$LOCATIONY = -1;
//Sets the decimal RGB ranges for binary conversion
$LOW = 100;
$MEDIUM = 150;
$HIGH = 200;
/*************** PROBABLY NO NEED TO EDIT BELOW HERE ***************/
//Checks to see if the image exists
if (strtolower(substr($IMAGESOURCE,0,7)) == "http://") {
$IMAGEHEADER = @get_headers($IMAGESOURCE);
if (!preg_match("|200|", $IMAGEHEADER0)) {
echo "ERROR:nnRemote Image Does Not Existnn";
exit;
}
} elseif (!file_exists($IMAGESOURCE)) {
