The template below displays child posts below any page content of the parent post with featured image thumbnails. Images are linked to child page. If there is an image before any page content on the child page, it will not display in order to avoid breaking the layout on posts with large images.

To display the images on the right side, change the class on this line (~ line 17):

genesis_image( array( 'format' => 'html', 'size' => genesis_get_option( 'image_size' ), 'attr' => array( 'class' => 'alignleft post-image' ) ) );

from

'class' => 'alignleft post-image'

to

'class' => 'alignright post-image'
