WooCommerce + Jetpack: Exclude Image From “Lazy Load”

If you don’t use an “Image Lazy Load” plugin, it’s time you install one. And if you happen to pick Jetpack’s free Lazy Load module, you probably did the right thing.

However, since I installed Jetpack Lazy Load, I noticed a little “jump” in my Storefront theme header section, where in fact there is an image – my Business Bloomer logo. The same might apply to any WooCommerce image: a category thumbnail, a single product featured image, a cart icon in the header, a homepage hero image, and so on.

Thankfully Jetpack has a useful “filter” you can tap into in order to exclude image classes from lazy loading (yes, I found this out today, it’s not that I know everything!). So, here’s the fix. Enjoy ๐Ÿ™‚

Jetpack: exclude an image from “Lazy Load” functionality

PHP Snippet: Exclude Image e.g. Logo From Jetpack Lazy Load

/**
 * @snippet       Avoid Lazy Loading an Image - Jetpack
 * @how-to        Get CustomizeWoo.com FREE
 * @author        Rodolfo Melogli
 * @compatible    WooCommerce 5
 * @community     https://businessbloomer.com/club/
 */

add_filter( 'jetpack_lazy_images_blacklisted_classes', 'bbloomer_exclude_custom_logo_class_from_lazy_load', 9999 );

function bbloomer_exclude_custom_logo_class_from_lazy_load( $classes ) {
	$classes[] = 'custom-logo';
	return $classes;
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101

  1. Hello,

    Thank you for this amazing script.

    I have one question, if I need to exclude several classes using the same function for example:
    custom-logo
    custom-mobile-logo
    category-image
    woocommerce-products-header

    How should I include them in the below section ?
    $classes[] = ‘custom-logo’;

    Regards,

    1. Hi Sally, you can try with (untested):

      $classes += array( 'custom-logo', 'category-image' );
  2. Hello Rodolfo,
    Thank you for this snippet, but now (12/2020) “jetpack_lazy_images_blacklisted_classes” is obsolete,
    you should use “jetpack_lazy_images_blocked_classes” instead.
    Best regards,
    Oly

    1. Excellent!

    1. Welcome!

  3. Hi Rodolfo,

    Thanks! This really helped me. You don’t need to specify priority and arguments.
    Default priority is 10 and default arguments accepted by an filter is 1.

    1. Hey Remzi, thanks for that! I wanted to use 999 to delay the call. If you add priority, you also need to add the arguments, however I’m not 100% sure about that part. I usually put none or both, it comes easier when I code. Cheers anyway ๐Ÿ™‚
