<h3 id="overview">Overview</h3>
<p>Add lazyLoad to plugin setup:</p>
<pre><code>lazyLoad: true</code></pre>
<p>LazyLoad HTML structure requires <code>class=&quot;owl-lazy&quot;</code> and <code>data-src=&quot;url_to_img&quot;</code> or/and <code>data-src-retina=&quot;url_to_highres_img&quot;</code>. If you set above settings not on <code>&lt;img&gt;</code> 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 <code>owl-lazy</code> class to the source tag and a data-srcset attribute.</p>
<h3 id="setup">Setup</h3>
<pre><code>$(&#39;.owl-carousel&#39;).owlCarousel({
items:4,
lazyLoad:true,
loop:true,
margin:10
});</code></pre>
<h3 id="option">Option</h3>
<p>If you want to preload images you can also add the option <code>lazyLoadEager</code> to the settings object, where the value indicates how many items to the right (and left, when loop is <code>true</code>) will be pre-loaded.</p>
