Thumbnail & Category link aside post

They are actually doing this is one loop, here’s an example to show similar structure.

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

    <div class="article">

        <div class="left">
            <?php the_post_thumbnail( $size, $attr ); ?>
            <?php get_the_category(); ?>
        </div><!-- end left side -->

        <div class="right">
            <?php the_excerpt(); ?>
        </div> <!-- end right side-->

    </div>

<?php endwhile; else: endif; ?>
