Peony - Read the Post button

  1. Go to your Wordpress dashboard > Genesis > Theme Settings.
  2. Find the Content Archives settings.
  3. Click on the drop-down box and choose “Display Post Excerpts.”
  4. Check the box that says "Include the Featured Image." Select the blog-image (700 x 9999) image size, or your preferred image size. Click Save Changes.
The "9999" height simply allows your featured images to display at their natural height relative to width. This gives you full control over how your images display on your blog. Whatever "shape" your original image is, that's what will show on the blog page.
