It just looks like your image is broken, can you put up a runnable
script + image in a tarball (or send it to me by mail) to verify?

More info:
- PHP is run as CGI
- using original windows binary pack
- php_gd2.dll from original windows binary pack
- web server: Apache 2.0.45
Imagecreatefrompng() is used in following code:
//$image_file_url ... URL to the source 24-bit PNG file
$image_base = ImageCreateTrueColor($map_width, $map_height);
$white = ImageColorExact($image_base, 255, 255, 255);
ImageFill($image_base, 0, 0, $white);
// ........
$input = fopen($image_file_url, "rb");
$image_data = fread($input, 2000000);
fclose($input);
$image_file = tempnam("", "gd".rand(0, 10000));
$output = fopen($image_file, "w+b");
fwrite($output, $image_data);
fclose($output);
$image_tmp = ImageCreateFromPNG($image_file); // ERROR
// ........

The error appears only if PHP is run as CGI (php.exe).
