One trick you can use is this, when you are inside a .js file it can be helpful, because php doesnt work.

Put the value of your php value inside a div as content, and then grab that in the javascript.

in the php file:

<div id="sVar" style="display:none;"><?php echo $s; ?></div>

in js:

var images = document.getElementById('sVar').innerHTML;
