così dovrebbe andare:

<?PHP 

class Image{ 

    var $src_filename; 

    var $src_width; 

    var $src_height; 

    var $src_type; 

    var $src_attr; 

    var $src_image; 

    var $final_width;
    var $final_height;  



    function Image($filename){ 

        $this->src_filename = $filename; 

        $this->GetImageInfo(); 

    } 



    function GetImageInfo(){ 

        list($this->src_width,$this->src_height, $this->src_type, $this->src_attr) = getimagesize($this->src_filename); 

    } 



    function CreateSourceImage(){ 

        switch($this->src_type){ 

            case 1: 

                $this->src_image =imagecreatefromgif($this->src_filename); 

                   break; 

            case 2: 

                $this->src_image =imagecreatefromjpeg($this->src_filename); 

            break; 

            case 3: 

                $this->src_image =imagecreatefrompng($this->src_filename); 

            break; 

            default:    return false; 

        } 



        return true; 

    } 



    function SaveProportionateImage($filename, $quality, $height){ 

        $dest_height = $height; 

        $ratio = $this->src_height / $dest_height; 

        // Salvo del dimensioni finali dell'immagine
        $this->final_width = $this->src_width / $ratio;
        $this->final_height = $this->src_height / $ratio;

        $dest_image = imagecreatetruecolor( $this->src_width / $ratio,$dest_height); 

        imagecopyresampled($dest_image, $this->src_image, 0, 0, 0, 0, 

            $this->final_width, 

            $this->final_height, 

            $this->src_width, 

            $this->src_height); 

        imagejpeg($dest_image, $filename.'.jpg', $quality); 

        imagedestroy($dest_image); 

    } 



    function Free(){ 

        imagedestroy($this->src_image); 

    } 

} 

?>

e nella tua pagina per recuperare i valori metti

echo "Larghezza finale: ". $img->final_width;
echo "\nAltezza  finale: ". $img->final_height;
