Hide image outside (above) loop when first post is a specific format

Hi,
I have an image at the top of my “index.php” page before the loop.
What I can’t seem to figure out how to do is stop the image from displaying if the first post has a specific format of, in my case, “aside”.

Can anyone help me with this?

Here’s a snippet of what the html structure looks like.
(minus irrelevant code for this dilemma)

<div class="featured-image">
	<img src="https://samdashton.co.uk/wp-content/uploads/2014/05/desk.jpg">
</div>

<?php if ( have_posts() ) : ?>
	<?php while ( have_posts() ) : the_post(); ?>
		<?php get_template_part( 'content', get_post_format() ); ?>
	<?php endwhile; ?>
<?php endif; ?>

Thanks ??
