Et par spørgsmål til mit upload og resize billede script

Jeg skrev koden lidt om, så den burde virke, men der sker ikke noget... dvs. gif-billedet bliver uploaded, men der laves ikke nogen thumb.

Der står i min PHP bog at imagegif kun virker på meget gamle GD lib's. -Så det er nok det, der er galt.

Hvad gør man så ?! Hvorfor findes den funktion ikke mere... Mit script ser sådan her ud nu:

move_uploaded_file($_FILES['uploadlogo']['tmp_name'], $_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
if($_FILES['uploadfile']['type'] == "image/gif") header('Content-type: image/gif');
elseif($_FILES['uploadfile']['type'] == "image/pjpeg") header('Content-type: image/jpg');
list($width, $height) = getimagesize($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
$new_width = 100;
$krympefaktor = $new_width/$width;
$new_height = round($height * $krympefaktor);
$image_blank = imagecreatetruecolor($new_width, $new_height);
if($_FILES['uploadfile']['type'] == "image/pjpeg") {
    $image = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
    imagecopyresampled($image_blank, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
    imagejpeg( $image_blank, $_SERVER['DOCUMENT_ROOT']."/cms/images/".basename($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name'], ".jpg")."_thumb.jpg", 85 );
    $newfilename = basename($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name'], ".gif")."_thumb.gif";
} elseif($_FILES['uploadfile']['type'] == "image/gif") {
    $image = imagecreatefromgif($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
    imagecopyresampled($image_blank, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
    imagegif( $image_blank, $_SERVER['DOCUMENT_ROOT']."/cms/images/".basename($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name'], ".gif")."_thumb.gif");
    $newfilename = basename($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name'], ".jpg")."_thumb.jpg";
}
$newfileurl = $_POST['uploadurl'];
writeFile($newfilename, $newfileurl);

HJÆLP :)

Ken jeg eventuelt lave gif-billedet om til jpg, når jeg kopierer det, og få det til at virke, eller er der en anden måde at lave gif-billeder ud af gif-billeder :)

Sært at der ikke var nogen, der ville kigge på det ??

Men efter 1½ time har jeg nu fået det fikset på denne måde:

move_uploaded_file($_FILES['uploadlogo']['tmp_name'], $_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
list($width, $height) = getimagesize($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
$new_width = 100;
$krympefaktor = $new_width/$width;
$new_height = round($height * $krympefaktor);
$destinationImage = imagecreatetruecolor($new_width, $new_height);
if($_FILES['uploadlogo']['type'] == "image/pjpeg") {
    $sourceImage = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
    imagecopyresampled($destinationImage, $sourceImage, 0, 0, 0, 0, $new_width, $new_height, imagesx($sourceImage), imagesy($sourceImage));
    imagepng($destinationImage, $_SERVER['DOCUMENT_ROOT']."/cms/images/".basename($_FILES['uploadlogo']['name'], ".jpg")."_thumb.jpg");
    $newfilename = basename($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name'], ".jpg")."_thumb.jpg";
} elseif($_FILES['uploadlogo']['type'] == "image/gif") {
    $sourceImage = imagecreatefromgif($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name']);
    imagecopyresampled($destinationImage, $sourceImage, 0, 0, 0, 0, $new_width, $new_height, imagesx($sourceImage), imagesy($sourceImage));
    imagepng($destinationImage, $_SERVER['DOCUMENT_ROOT']."/cms/images/".basename($_FILES['uploadlogo']['name'], ".gif")."_thumb.gif");
    $newfilename = basename($_SERVER['DOCUMENT_ROOT']."/cms/images/".$_FILES['uploadlogo']['name'], ".gif")."_thumb.gif";
}
$newfileurl = $_POST['uploadurl'];
writeFile($newfilename, $newfileurl);

Det er jo smukt :)
