JQuery for Image Swap On Hover – Need Simple Adjustment

Currently I have this JQuery document in my theme’s JS folder to allow me to hover over images and swap them to the featured image like so:

https://test.pillarsoflifebook.com/tables/tabletops/wood/rustic-plank-oak/rustic-plank-oak/

function myFunction() {
    var $large = jQuery('#largeImage');

    //store the default image as the data src
    $large.data('src', $large.attr('src'));

    var src = jQuery('#largeImage').attr('src');
    jQuery('#thumbs img').hover(function () {
        $large.attr('src', jQuery(this).attr('src').replace('thumb', 'large'));
    }, function () {
        //on mouse leave put back the original value
        $large.attr('src', $large.data('src'));
    });
}

jQuery(document).ready(function () {
    jQuery(myFunction);
});

For another page in my clients site I need the same function WITHOUT the featured image returning to the original. Hence .. when you hover and the featured image changes … it needs to remain changed when you hover off again.

Should I add another script (pretty much the same with minor adjustments) for this?

Thank you!
