添加属性到图像加载功能

I'm using "Rocket Lazy Load" plugin to lazy loading my images but it is incompatible with sliders. In the plugin page in wordpress.org, is said: you should add 'data-no-lazy="1"' property to your image tag then it won't be effected. My picture calling function is:

<?php the_post_thumbnail('thumbnail-blog-featured', array('title' => "")); ?>

How can I add the mentioned property to my slider images?

Very simple, you can add attribute like below:

 the_post_thumbnail( 'thumbnail-blog-featured', array( 'title' => get_the_title(),
    'data-no-lazy' => '1' ) );
