Need help with a function code

[GameForAdult]

Anybody here who can help me out with this? I'm working on a new layout but stuck with one code.

I need to change the function so it includes this code

<img class="lazy" data-original="img/example.jpg" width="190" height="140">

into this function

$thumb = "<img src=\"$thumb\" $rotate_thumbs id=\"$prefix-".get_the_ID()."\" alt=\"".esc_attr($title)."\">";

Thanks

$thumb = '<img class=lazy data-original="'.$thumb.'" src="pixel.gif?" width="190" height="140"  '.$rotate_thumbs.' id="'.$prefix.'-'.get_the_ID().'" alt="'.esc_attr($title).'">';
