imagepng dont display both in ff and ie

[cityboy101]

 

i have this issue:

 

showpic.php

================================================

$ch = curl_init();

$timeout = 0;

curl_setopt ($ch, CURLOPT_URL, $xmyurl);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

// Getting binary data

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);

 

$image = curl_exec($ch);

curl_close($ch);

 

header('Content-type: image/png');

$xim=@imagecreatefromstring($image);

 

$xbase = @imagecreatetruecolor(130,168);

$xback=imagecolorallocate($xbase, 255,255,255);  //green

imagefill($xbase,0,0,$xback);

 

$xhead=@imagecreatefrompng('xhead.png');

imagecopy($xbase,$xhead,10,0,0,0,108,28);

imagecopy($xbase,$xim,0, 28, 0, 0, 130,140);

imagepng($xbase);

================================================

 

then i have this code to display the pic:

 

echo'

<font color="#FF0000" size="4">Congratulations!!!</font><br>

                    <span style="font-weight: 400"><font size="2">

                    <font color="#000000">Here is your pic ;-)</font><br>

                    </font></span>

                    <img src="showpic.php?xurl='.$newurl.'">

                    ';

 

the issue is, on my machine both on ie and ff the image display perfectly.

however on some machines it doesnt display the entire pic just the $xhead value.

what is wrong with it? can some pls tell me how to fix this problem?
