Custom Fields Lazy Load

Hi!

I’m using Advanced Custom Fields plugin for my images. I understand that BJ Lazy Load should be able to lazy load these images as well using this code:

<?php
$img_html = '<img src="myimage.jpg" alt="">';
$img_html = apply_filters( 'bj_lazy_load_html', $img_html );
echo $img_html;
?>

However, I don’t know were on my WordPress site to put it?
Much appreciate some help.
