thumbnails not showing up in search page

[chawk]

What should I add to this shop/search.html page to get the images to show up? 

{% if not category %}

<h4>{% trans "Products" %}</h4>

{% endif %}

<ul>

{% for product in results.products %}

       <li><a href="{{ product.get_absolute_url }}">{{ product.translated_name }}</a> {% trans "for" %} {{ product|discount_price:storewide_sale|currency}}</li>

   {% endfor %}

</ul>

{% else %}

Sorry, i am learning, the answer is that I did not include 

{% load thumbnail %} 

at the top of the html template
