[Theme: Bromine] How to change position of featured image ?

Hello everybody,
I have a problem, when I post in my blog the featured image of post is on the top of title, I want that this image will be on the right side, text on the left side and the title on the top of the post.
How I understand it’s written in content.php file … But i don’t understand how to change it.

content.php:

<?php
/**

    <header class="post-header">
        <div class="header-metas">

            <?php bro_post_format(); ?>

            <?php if( is_singular() ) { edit_post_link( __( 'Edit', 'bromine' ), '<span class="edit-link">', '</span>' ); } ?>

            <span class="post-date">
                <time class="published" datetime="<?php echo get_the_time('c'); ?>"><a title="<?php _e( 'Permalink to: ', 'bromine' ); echo the_title(); ?>" href="<?php the_permalink(); ?>"><?php echo get_the_date(); ?></a></time>
            </span>

        </div>

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