Symfony2 Image file upload - doctrine

Question

I am trying to handle image uploads via a form and then display these image uploads elsewhere in my website.
So far I have been looking at the Cookbook and also at other tutorials.I have created an Entity and a Form and am able to submit , but I am not sure if I am storing the file itself in my DB or just the name of it.
When I try to display the images in my view resource not found error on the images. Any suggestions on the correct way to upload images in Symfony?
and this is what I have so far. Entity
<?php
namespace BlogBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

You are only storing the path in the DB, and only it's necesary that.
Using path you can show the file in your view
pd: you are storing the file in your server with:
$this->file->move(
$this->getUploadRootDir(),
$this->getFile()->getClientOriginalName()
);
