imagepng dont display both in ff and ie

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?

 

Why are you using font tags?

 

do you have same libraries on all machines? check for missing ones , curl/gd.
