Embed Instagram feed to emails - widgets

I have embedded the instagram feed for our store to email template, however the posts are different sizes depending on whether content is a real, photo etc. I also want the posts to be centred which they aren’t.

I want the images to appear uniform, like they do under WIDGET tab in rss.

How can I achieve this?

This is the KLAVIO code we used:

<div>{% for item in feeds.FEED_NAME.rss.channel.item|slice:":3" %}
    <table style="display:inline-block; margin-left:auto; margin-right:auto">
	<tbody>
	    <tr>
		<td style="width:150px; text-align: center;"><a href="{{ item.link }}">
		  <img style="max-width: 150px; height: auto;" src="{% if item|lookup:'media:content'|lookup:'0'|lookup:'@url' %}{{ item|lookup:'media:content'|lookup:'0'|lookup:'@url' }}{% else %}{{ item|lookup:'media:content'|lookup:'@url' }}{% endif %}" style="margin: 1px; max-width: 150px; height: auto;" /></a>
		</td>
	    </tr>
	</tbody>
    </table>
{% endfor %}</div>
