在Controller

$images = array(); 
$em = $this->getDoctrine->getManager(); 
$probleme = $em->getRepository('PiCrowdRiseWebBundle:Probleme')->findAll(); 
foreach ($probleme as $key => $entity) { 
    $images[$key] = base64_encode(stream_get_contents($entity->getFoto())); 
} 

// ... 

return $this->render('PiCrowdRiseWebBundle:Probleme:problemList.html.twig', array(
    'problemes' => $probleme, 
    'images' => $images, 
)); 

查看：

{% for key, entity in problemes %} 
    {# ... #} 
    <img alt="Embedded Image" src="data:image/png;base64,{{ images[key] }}" /> 
    {# ... #} 
{% endfor %}
