The site is at http://h-book.info.
The excerpt of the latest post on the front page does not include its image, though the theme's example/demo screenshot shows that the image should show up.
From research, apparently it may have something to do with this code in the home.php file:
<?php if ( $morningafter_options['show_full_home'] == "1" ) the_content( __( 'Continue reading <span class="meta-nav">»</span>', 'woothemes' ) ); else the_excerpt(); ?>
Changing the_excerpt() to the_content() and adding <!--more--> to the place in the full post that I want the excerpt to end does not work. It simply puts the entire post on the front page and overlaps it with the middle column.
Also, there does not seem to be an "excerpt" field in the post's editor.
After hours of searching for a solution, I would very much appreciate any help anyone can give.
Never mind! Figures that right as I finally caved and posted asking for help, I'd find the solution. I'll leave this post up, in case it helps someone else.
I used the "Featured Image" link at the bottom right corner of the post's Edit page, and just chose the image I'd already inserted into the post from the Media Gallery.
