Image above footer

Hi there,
first of all I apologize for my English, I know it's not the best...
I'm trying to add an image just above the widget footer area and below the container.
I edited the footer.php file (child theme) and just under

<?php
/**
 * The template for displaying the footer.
 *
 * @package GeneratePress
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly.
}
?>

	</div>
</div>

I added this line of code:
--- img src="/wp-content/uploads/footer.png" alt="footer silhouette" width="2000" height="122" ---
I don't know if this is the best way to do what I want to do...
Anyway, as you can see on my site, there is awhite space between the widget foote area and the image.
How can I hide that white space?
Thank you.
