How to put the post title above the feature image?

The display of the featured image and post title are contained in the file content.php. This file is pulled into both index.php – which controls the blog index – and single.php – which controls single posts.

Lines 9-17 define the display of the featured image:

<?php if ( '' != get_the_post_thumbnail() ) : ?>
<?php if ( ! is_single() ) : ?>
<a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( sprintf( __( 'Permalink to %s', 'ryu' ), the_title_attribute( 'echo=0' ) ) ); ?>" rel="<?php the_ID(); ?>" class="ryu-featured-thumbnail">
<?php the_post_thumbnail( 'ryu-featured-thumbnail' ); ?>
</a>
<?php else : ?>
<?php the_post_thumbnail( 'ryu-featured-thumbnail' ); ?>
<?php endif; ?>
<?php endif; ?>

Lines 19-31 control the display of the entry header section, which includes the post title:

<header class="entry-header">
<?php
 $categories_list = get_the_category_list( __( ', ', 'ryu' ) );
 if ( $categories_list && ryu_categorized_blog() )
   echo '<span class="categories-links">' . $categories_list . '</span>';

 if ( ! is_single() ) :
 the_title( '<h1 class="entry-title"><a href="' . esc_url( get_permalink() ) . '" rel="bookmark">', '</a></h1>' );
 else :
the_title( '<h1 class="entry-title">', '</h1>' );
endif;
?>
</header><!-- .entry-header -->

This should point you in the right direction. Now you can make a copy of content.php in your child theme and rearrange the elements to get the display looking how you want.
