It appears that your post is using both a featured image and an image embedded in the post content. Probably the easiest option is to remove the image from the content, then change the post format from Standard to Image so it will display the featured image. Then you just need to move the author by-line below the image:
1. Copy single.php to your child theme.
2. Find this near the top of the code:
<div class="post-inner group">
<h1 class="post-title"><?php the_title(); ?></h1>
<p class="post-byline"><?php _e('by','hueman'); ?> <?php the_author_posts_link(); ?> · <?php the_time(get_option('date_format')); ?></p>
<?php if( get_post_format() ) { get_template_part('inc/post-formats'); } ?>
<div class="clear"></div>
3. Move the “post-byline” line so it’s below the get_post_format() line:
<div class="post-inner group">
<h1 class="post-title"><?php the_title(); ?></h1>
<?php if( get_post_format() ) { get_template_part('inc/post-formats'); } ?>
<p class="post-byline"><?php _e('by','hueman'); ?> <?php the_author_posts_link(); ?> · <?php the_time(get_option('date_format')); ?></p>
<div class="clear"></div>
4. In your Shareaholic plugin set the Share Buttons location for Post to Above Content.
