title: Feature-image not showing for posts Jekyll
body: <p>I am building a Jekyll site and would like to have feature-imgs on posts show page. I thought I had the Front matter correct with the right file path to my image but for some reason the image still won't show up. </p>
  
  <p>Front matter</p>
  
  <pre><code>---
  layout: post
  title: My Coding Journey
  feature-img: "/img/journey.png"
  ---
  </code></pre>
  
  <p>My images are in a folder in project root called img.</p>
  
  <p>Post layout:</p>
  
  <pre><code>---
  layout: post-header
  ---
  &lt;article {% if page.feature-img %} class="feature-image"{% endif %}&gt;
    &lt;section class="post-content"&gt;{{ content }}&lt;/section&gt;
  &lt;/article&gt;
  
  &lt;!-- Disqus --&gt;
  {% if site.theme_settings.disqus_shortname %}
  &lt;div class="comments"&gt;
    {% include disqus.html %}
  &lt;/div&gt;
  {% endif %}
  </code></pre>
  
  <p>Any idea why the feature image is not working. </p>
