Narrative Theme - Feature slider Image size

Hi all,

Trying to change the size of the image in the Feature Slider block.

See the size of the box is constrained to 326x326 - I’d love it to be say 500x500 to make the image fill a bit more of the page

I feel like the answer is in the liquid code but I can’t make it out - would love some pointers.


      {% for block in section.blocks %}
        

          

            {% if block.settings.show_image %}
              {% if block.settings.slide_image %}
                

                  {% assign img_url = block.settings.slide_image | img_url: '1x1' | replace: '_1x1.', '_{width}x.' %}
                  
                

              {% else %}
                {% capture placeholder_class %}placeholder-svg placeholder-svg-{{ forloop.index }} featured-slider__slide-image{% endcapture %}
                {{ 'product-' | append: forloop.index | placeholder_svg_tag: placeholder_class }}
              {% endif %}
            {% endif %}
            {% if block.settings.slide_title != blank %}
              ### {{ block.settings.slide_title }}
            {% endif %}

            {% if block.settings.slide_button_text != blank %}
              {{ block.settings.slide_button_text }}
            {% endif %}
          

        

      {% endfor %}
    

Thanks
