Retrieve images in cells using Google Sheets API
<p>I'm using the Google Sheets API to return the JSON of a Google Sheet,</p>

<p>e.g </p>

<pre><code> var url = 'https://spreadsheets.google.com/feeds/list/' + id + '/od6/public/values?alt=json';
</code></pre>

<p>In one of the cells I have added an image, but this appears empty in the json.<br>
How can I retrieve this image?</p>
