A more direct way, without extra work in the controller:

In the Entity Class

/**
 * @ORM\Column(name="photo", type="blob", nullable=true)
 */
private $photo;

private $rawPhoto;

public function displayPhoto()
{
    if(null === $this->rawPhoto) {
        $this->rawPhoto = "data:image/png;base64," . base64_encode(stream_get_contents($this->getPhoto()));
    }

    return $this->rawPhoto;
}

In the view

EDIT

Thanks to @b.enoit.be answer to my question here, I could improve this code so the image can be displayed more than once.
