problems with GD library after migration

[Emran_Omar]

hi everybody,

i get a funny and very big problem !!!
i was running my explication in a web server (LINUX) and after this i´m running it in a new server (windows 2008 64bits).

the big problem i get is, i have the same MySQL server, the same data, the same PHP server, the same script, but the only difference is my OS.

here is the phpinfo from the new server:
im[dot]intercultural[dot]com[dot]br/im/phpinfo.php

here is the phpinfo from the old server
[dot]intercultural[dot]com[dot]br/dev/phpinfo.php

here the script running in the new server:
im[dot]intercultural[dot]com[dot]br/im/clientes/mostraFoto.php?sessionid=&id_foto_pais=97&tamanho=150

here the script running in the old server:
intercultural[dot]com[dot]br/im/clientes/mostraFoto.php?sessionid=&id_foto_pais=97&tamanho=150

and here is the code

<?

$path = "../";
include_once ($path."includes/config.inc.php");
include_once ($path."includes/db_generico.inc.php");
include_once($path."includes/utils.inc.php");



  // Variáveis passadas por POST/GET
  $sIdFotoPais = $_REQUEST['id_foto_pais'];
  $sIdFotoCidade = $_REQUEST['id_foto_cidade'];
  $sIdFotoEscola = $_REQUEST['id_foto_escola'];
  $sIdFotoHigh = $_REQUEST['id_foto_high'];
  $sIdFotoEscolaFerias = $_REQUEST['id_foto_escola_ferias'];




  $conexao = bd_conecta($config["db"]);
  if ( $sIdFotoPais != "" ) {
	  $sQuery = "select arquivo,arquivo_tipo,arquivo_tamanho,arquivo_nome from inter_imagens_paises where id_imagem='$sIdFotoPais'";
  }
  else if ( $sIdFotoCidade != "" )  {
	  $sQuery = "select arquivo,arquivo_tipo,arquivo_tamanho,arquivo_nome from inter_imagens_cidades where id_imagem='$sIdFotoCidade'";  

 }
  else if ( $sIdFotoEscola != "" )  {
	  $sQuery = "select arquivo,arquivo_tipo,arquivo_tamanho,arquivo_nome from inter_imagens_escolas where id_imagem='$sIdFotoEscola'";  

 }
 else if($sIdFotoHigh > 0){
 	$sQuery = "select arquivo,arquivo_tipo,arquivo_tamanho,arquivo_nome from inter_imagens_high where id_imagem='$sIdFotoHigh'";  

 }
 else if($sIdFotoEscolaFerias > 0){
	 $sQuery = "select arquivo,arquivo_tipo,arquivo_tamanho,arquivo_nome from inter_imagens_escolas_ferias where id_imagem='$sIdFotoEscolaFerias'";  

 }

  if ($rs = bd_executaQuery($conexao,$sQuery,$config["db"])) {
    $linha = bd_array($rs);
    $sArquivo = $linha["arquivo"];
    $sTipo = $linha["arquivo_tipo"];
    $sTamanho = $linha["arquivo_tamanho"];
    $sNomeArquivo = $linha["arquivo_nome"];
  }
  bd_desconecta($conexao);

  // redimensiona para o tamanho informado
	$binary = $sArquivo;

$gdHandler = imagecreatefromstring($binary);



$width = imagesx($gdHandler);
$height = imagesy($gdHandler);

if ($width > $height) {
	if ($width > $tamanho) {
		$ratio = $tamanho / $width;
	} else {
		$ratio = 1;
	}
} else {
	if ($height > $tamanho) {
		$ratio = $tamanho / $height;
	} else {
		$ratio = 1;
	}
}

$newWidth = round($tamanho);
$newHeight = round($height * $ratio);

$newGdHandler = imagecreatetruecolor($newWidth, $newHeight);

imagecopyresampled($newGdHandler, $gdHandler, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

header("Content-Type:".$sTipo);
imagejpeg($gdHandler, '', 60);
?>

i already try to get the data from the old DB server (MySQL) and run it in the new server, but it did not work, i try the other wise, get the data from the new DB server (MySQL) and run it in the old server and it work, so i believe the problem is not in the MYSQL codification or something like that but is with the PHP server.

other difference is, i was running apache in the old server and now running IIS 7

so please, any one can gave me any help ? i had tried almost everything i found in the internet and didn´t succeed, i´m dealing with this problem since last week and i dont know what else i can do to fix it.

tks a lot !!!
