Is Smart LazyLoad compatible with caching and optimization plugins?
Yes. It works well with most caching, CDN, and optimization plugins.
Is this plugin SEO-friendly?
Yes. Smart LazyLoad preserves original content using noscript fallbacks, supports native lazy loading, and allows skipping the first image for better LCP performance.
Does it support background images?
Yes. Smart LazyLoad can automatically lazy-load background images defined via the style attribute, such as:
<div style="background-image: url(image-slug.jpg);">
You can also apply it manually yourself.
Simply add this special markup to the element on which you want to apply lazy loading:
<div class="mozedia-lazyload" data-bg="url(../img/image-slug.jpg)"></div>
Or conditionally disable it:
add_action( 'wp', 'disable_mozedia_lazyload' );
function disable_mozedia_lazyload() {
if ( is_single() ) {
add_filter( 'do_mozedia_lazyload', '__return_false' );
}

Simply add this special markup to the element on which you want to apply lazy loading:
<div class="mozedia-lazyload" data-bg="url(../img/image-slug.jpg)"></div>
add_filter( 'mozedia_svg_placeholder', 'mozedia_replace_image_placeholder');
function mozedia_replace_image_placeholder() {
return 'data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"></svg>';
}
Lazy loaded iframes use a separate placeholder value (default: about:blank).
You can customize the iframe placeholder using the following filter:
add_filter( 'mozedia_lazyload_placeholder', function () {
return 'about:blank';
});
function mozedia_replace_image_placeholder() {
return 'data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"></svg>';
}

add_filter( 'mozedia_lazyload_placeholder', function () {

});
