query last image in shopify liquid -

-

i’m trying add link size guide image having pull last image collection.

but right it’s pulling images, not last. how pull last?

 <!-- size guide -->          <div id=“size_guide”>  {% image in product.images %}  <a href=“{{ image.src | product_img_url: ‘master’ }}” class=“fancybox-media {% cycle ‘,last’ %}”>  size guide</a> {% endfor %}           </div>  </div>

try using last array filter. e.g:

<a href="{{ product.images.last | product_img_url: 'master' }}">size guide</a>
