### 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
});
```
### Option
If you want to preload images you can also add the option ```lazyLoadEager``` to the settings object, where the value
indicates how many items to the right (and left, when loop is ```true```) will be pre-loaded.
### HTML:
```
<div class="owl-carousel owl-theme">
<img class="owl-lazy" data-src="https://placehold.it/350x450&text=1" data-src-retina="https://placehold.it/350x250&text=1-retina" alt="">
