What if you move the header bit, and try to view the php file directly?
Sending a header before any errors may be outputted can screw up your
possibility to see the errors.
<?php
$im = @imagecreate(100, 50)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color) or
die('Cannot create text');
header("Content-type: image/png");
imagepng($im);
imagedestroy($im);
?>
It works here BTW, without problems.
Could you maybe give us the GD bit's of phpinfo() from the different
servers?
