Wordpress: Si elimino footer no me funciona plugin Lazy Load

[Luisa29]

Hola amigos, resulta que si elimino el footer del código el plugin Lazyload deja de funcionar y no se ven las fotos en el blog. ¿Cómo podría eliminar u ocultar el footer sin que suceda esto?

Código del footer:

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

</div><!-- #main -->
<footer id="colophon" class="site-footer" role="contentinfo">
<?php get_sidebar( 'main' ); ?>

<div class="site-info">
<?php do_action( 'twentythirteen_credits' ); ?>
<a href="<?php echo esc_url( __( 'http://wordpress.org/', 'twentythirteen' ) ); ?>" title="<?php esc_attr_e( 'Semantic Personal Publishing Platform', 'twentythirteen' ); ?>"><?php printf( __( 'Proudly powered by %s', 'twentythirteen' ), 'WordPress' ); ?></a>
</div><!-- .site-info -->
</footer><!-- #colophon -->
</div><!-- #page -->

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

El código del índice, si elimino de él <?php get_footer(); ?> sucede lo mismo:

<?php
/**
* The main template file
*
* This is the most generic template file in a WordPress theme and one of the
* two required files for a theme (the other being style.css).
* It is used to display a page when nothing more specific matches a query.
* For example, it puts together the home page when no home.php file exists.
*
* @link http://codex.wordpress.org/Template_Hierarchy
*
* @package WordPress
* @subpackage Twenty_Thirteen
* @since Twenty Thirteen 1.0
*/

get_header(); ?>

<div id="primary" class="content-area">
<div id="content" class="site-content" role="main">
<?php if ( have_posts() ) : ?>

<?php /* The loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', get_post_format() ); ?>
<?php endwhile; ?>

<?php twentythirteen_paging_nav(); ?>

<?php else : ?>
<?php get_template_part( 'content', 'none' ); ?>
<?php endif; ?>

</div><!-- #content -->
</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

El código del plugin Lazyload:

<?php
/**
* Plugin Name: Lazy Load
* Description: Lazy load images to improve page load times. Uses jQuery.sonar to only load an image when it's visible in the viewport.
* Version: 0.5
*
* Code by the WordPress.com VIP team, TechCrunch 2011 Redesign team, and Jake Goldman (10up LLC).
* Uses jQuery.sonar by Dave Artz (AOL): http://www.artzstudio.com/files/jque.../jquery.sonar/

*/

if ( ! class_exists( 'LazyLoad_Images' ) ) :

class LazyLoad_Images {

const version = '0.5';

static function init() {
if ( is_admin() )
return;

add_action( 'wp_enqueue_scripts', array( __CLASS__, 'add_scripts' ) );
add_filter( 'the_content', array( __CLASS__, 'add_image_placeholders' ), 99 ); // run this later, so other content filters have run, including image_add_wh on WP.com
add_filter( 'post_thumbnail_html', array( __CLASS__, 'add_image_placeholders' ), 11 );
add_filter( 'get_avatar', array( __CLASS__, 'add_image_placeholders' ), 11 );
}

static function add_scripts() {
wp_enqueue_script( 'wpcom-lazy-load-images', self::get_url( 'js/lazy-load.js' ), array( 'jquery', 'jquery-sonar' ), self::version, true );
wp_enqueue_script( 'jquery-sonar', self::get_url( 'js/jquery.sonar.min.js' ), array( 'jquery' ), self::version, true );
}

static function add_image_placeholders( $content ) {
// Don't lazyload for feeds, previews, mobile
if( is_feed() || is_preview() || ( function_exists( 'is_mobile' ) && is_mobile() ) )
return $content;

// Don't lazy-load if the content has already been run through previously
if ( false !== strpos( $content, 'data-lazy-src' ) )
return $content;

// In case you want to change the placeholder image
$placeholder_image = apply_filters( 'lazyload_images_placeholder_image', self::get_url( 'images/1x1.trans.gif' ) );

// This is a pretty simple regex, but it works
$content = preg_replace( '#<img([^>]+?)src=[\'"]?([^\'"\s>]+)[\'"]?([^>]*)>#', sprintf( '<img${1}src="%s" data-lazy-src="${2}"${3}><noscript><img${1}src="${2}"${3}></noscript>', $placeholder_image ), $content );

return $content;
}

static function get_url( $path = '' ) {
return plugins_url( ltrim( $path, '/' ), __FILE__ );
}
}

function lazyload_images_add_placeholders( $content ) {
return LazyLoad_Images::add_image_placeholders( $content );
}

LazyLoad_Images::init();

endif;

¿Cómo podría eliminar el footer (u ocultarlo) sin que suceda esto? Gracias !
