将图像另存为blob类型

Question

I have used MySQL to save a image as a blob type. I 'm uploading files through PHP and when I get the image back I revive only a part of it. How can I improve the max size ? (my image file size is less than 300 KB)

PHP uploader...

if($_FILES!=null && $_POST!=null){
    $file = $_FILES["image"]["tmp_name"];   

    if(!isset($file)){
        echo "Please upload an image";
    }else{
        $image = addslashes(file_get_contents($_FILES['image']['tmp_name']));

        $image_name = addslashes($_FILES['image']['name']);
        $type=$_POST['type'];

        $image_size = getimagesize($_FILES['image']['tmp_name']);

        if($image_size==FALSE)
            echo "That's not an image.";
        else
        {

            if(!(mysql_query("INSERT INTO store (name,image,type) values  ('$image_name','$image','$type')")))
                echo "Problem uploading image";
            else
            {
                $lastid = mysql_insert_id();
                echo "Image uploaded. <p /> Your image: <p /> <img id='imageId' src=get.php?id=$lastid>";
            }
        }
    }
  }

retrieving image

$id = addslashes($_REQUEST['id']) ;

$imageRow = mysql_query("SELECT * FROM store WHERE id=$id");

$image = mysql_fetch_assoc($imageRow);
$image = $image['image'];

header("Content-type: image/jpg");


echo $image;

You can use different types of blobs. Blob, Mediumblob, longblob, etc.
