Lazy loading free module PrestaShop 1.5 - 1.7

how to make it works ?

install it first, than, modify all images you want to display with it and replace:

<img src="path/to/image">

BY:

<img class="lazy" data-src="path/to/image">

for ajax content

use $(document).trigger('needLazy') for execute the plugin.

And it works.
