Assets in Super Table not working
Ah ok, two issues;


the image field is an array so you need to just select the first
you need an 'img' html tag as the twig code will only output the url


{% for entry in craft.entries.section('blog').level(1) %}

  &lt;h2 class="under"&gt;{{ entry.title }}&lt;/h2&gt;
  {{ entry.getLink() }}
  {{ entry.previewText |raw }}
  {% for row in entry.textImages.all() %}
    &lt;img src="{{ row.textImage.one().url() }}"&gt;
    &lt;br /&gt;
    {{ row.textImageWitdh }}
  {% endfor %}

{% endfor %}
