title: How to get book cover picture through amazon API
body: <p>I want to get the cover of a book form its ASIN through Amazon API. I use the <code>ItemLookup</code> function, but I only get the <code>author</code>, <code>manufacturer</code> and the <code>title</code>.</p>
  
  <p>ie :</p>
  
  <pre><code>&lt;ItemAttributes&gt;
  &lt;Author&gt;Anna Gavalda&lt;/Author&gt;
  &lt;Manufacturer&gt;J'Ai Lu&lt;/Manufacturer&gt;
  &lt;ProductGroup&gt;Book&lt;/ProductGroup&gt;
  &lt;Title&gt;Ensemble, C'Est Tout (French Edition)&lt;/Title&gt;
  &lt;/ItemAttributes&gt;
  </code></pre>
