Prevent other versions of jquery from loading on static front page

Maybe I am on thin ice but lets try.

Assuming that you already have the correct jquery version(you want to use) downloaded and copied to a folder.
(The same js folder as the jquery.rwdImageMaps.js would be logical imho)

Imho you also can delete folowing code part <script type="text/javascript" src="https://wordpress.stackexchange.com/questions/195723/<?php echo get_stylesheet_directory_uri(); ?>/js/jquery.rwdImageMaps.js"></script>
from that front-page.php file and load it together with the (‘new’)jQuery and migrate file into the footer.
When you do not want that, please delete the 2 lines below //To load the jquery.rwdImageMaps.js file also into the footer

You could use following function.(I assume you downloaded both files, the normal and minified jQeury file), (use false,true to go into footer false,false to go into head)

Please copy this function in the functions.php (in your child-theme folder)

function load_scripts_into_footer() {
    // Only load on front-page.php (else it could brake some?)
    if ( is_front_page() ){

        // Deregister the undesirable jQuery file WP uses itself
        wp_deregister_script( 'jquery' );

        // The Version2 jQuery file
        wp_register_script( 'jquery-2.0.0.min', get_stylesheet_directory_uri() . '/js/jquery-2.0.0.min.js', array(), false, true ); 
        wp_enqueue_script(  'jquery-2.0.0.min', get_stylesheet_directory_uri() . '/js/jquery-2.0.0.min.js', array(), false, true );

        // It is recommend to use jquery-migrate in this case
        wp_enqueue_script(  'jquery-migrate.min', '/wp-includes/js/jquery/jquery-migrate.min.js', array('jquery-2.0.0.min'), false, true );

        // To load the jquery.rwdImageMaps.js file also into the footer
        wp_register_script( 'jquery.rwdImageMaps', get_stylesheet_directory_uri() . '/js/jquery.rwdImageMaps', array('jquery-2.0.0.min','jquery-migrate.min'), false, true );
        wp_enqueue_script(  'jquery.rwdImageMaps', get_stylesheet_directory_uri() . '/js/jquery.rwdImageMaps', array('jquery-2.0.0.min','jquery-migrate.min'), false, true );
    }
}
// Action hook
add_action( 'wp_enqueue_scripts', 'load_scripts_into_footer' );

I have not tested it but it should work imho. Give it a try I would say.
