Lazy Load

Overview

Add lazyLoad to plugin setup:

lazyLoad: true

LazyLoad HTML structure requires class="owl-lazy" and data-src="url_to_img" or/and data-src-retina="url_to_highres_img". If you set above settings not on <img> but on other DOM element then Owl will load an image into css inline background style. You can even use picture tags with different sources by adding the owl-lazy class to the source tag and a data-srcset attribute.

Setup

$('.owl-carousel').owlCarousel({
    items:4,
    lazyLoad:true,
    loop:true,
    margin:10
});

HTML:

<div class="owl-carousel owl-theme">
    <img class="owl-lazy" data-src="https://placehold.it/350x250&text=1" data-src-retina="https://placehold.it/350x250&text=1-retina" alt="">
    <img class="owl-lazy" data-src="https://placehold.it/350x250&text=2" data-src-retina="https://placehold.it/350x250&text=2-retina" alt="">
