        if($_FILES['upimage']['type']>210000){
            echo "你上传的文件体积超过了限制最大不能超过200K";
            exit();
        }
        $fileext = array("image/pjpeg","image/gif","image/x-png");

        if($im = @imagecreatefrompng($_FILES['upimage']['tmp_name']) or $im = @imagecreatefromgif($_FILES['upimage']['tmp_name']) or $im = @imagecreatefromjpeg($_FILES['upimage']['tmp_name'])){
            $imginfo = @getimagesize($_FILES['upimage']['tmp_name']);
            if(!is_array($imginfo)){
                echo "图形格式错误！";
            }
