How to use?

Just activate the plugin. Additional settings is not required.

What is lazy loadind?

Lazy loading is the strategy of loading resources as they are needed, rather than in advance. This approach frees up resources during the initial page load and avoids loading assets that are never used.
Images that are offscreen during the initial pageload are ideal candidates for this technique.

How To minimize content jumping or unpredictable behavior images before loading?

Add width and height attributes to image.

<img width="200" height="100" src="image.jpg">
How to lazyload a background image?

In case you want to lazyload a background image via a class you can do so by using the addClasses option:

<style>
        .bg-stage.lazyloaded {
            background-image: url(lazyloaded-bg.jpg);
        }
      </style>

      <div class="bg-stage lazyload">
        <!-- content -->
      </div>

Прекрасно работает, адекватно реагирует на быстрый скролл! У меня на одной из страниц выводится 300+ изображений(с помощью плагина NextGEN Gallery) и после активации плагина страница загружается намного быстрее! Картинки не "скачут", плавно появляются при скролле страницы. Я очень доволен работой этого плагина!!! Большое спасибо автору!

НО после сегодняшнего обновления до версии 1.4 перестал отображать вставки iframe вовсе! Только белое пустое место. Отключаешь медленную загрузку iframe в настройках - все хорошо. Пожелания - хотелось бы пояснения в настройках к каждому пункту.

Отличный плагин. Очень хорошо продуман, совместим с многими плагинами, прост и понятен в настройках. Спасибо автору за труд!
