add sitelock icon to footer.php

I purchased sitelock and am now trying to add it to my footer.php page. But am not sure where to put it since I am still learning wp.  I tried putting the div tag in various places in the footer but it never displays.  Not sure what the problem is.  Can someone advise me as to where I put the div tag.

<?php
/**
 * The template for displaying the footer
 *
 * Contains footer content and the closing of the #main and #page div elements.
 *
 * @package WordPress
 * @subpackage Twenty_Twelve
 * @since Twenty Twelve 1.0
 */
?>



	</div><!-- #main .wrapper -->
	<footer id="colophon" role="contentinfo">
		<div class="site-info">
			<?php do_action( 'twentytwelve_credits' ); ?>
			<a href="<?php echo esc_url( __( 'http://wordpress.org/', 'twentytwelve' ) ); ?>" title="<?php esc_attr_e( 'Semantic Personal Publishing Platform', 'twentytwelve' ); ?>"><?php printf( __( 'Designed by Nsite Designs | Powered by %s', 'twentytwelve' ), 'WordPress' ); ?></a>
		
		</div><!-- .site-info -->
		
		
	</footer><!-- #colophon -->
</div><!-- #page -->



		

<?php wp_footer(); ?>
</body>
</html>
