Shutter zoom-image problems

I have a Next-Gen generated gallery with a Shutter (lightbox-like) effect, in which I want a hover zoom overlay with the full-size image. I use featuredimagezoomer.js for the zooming effect.

The problem with the script is that it doesn’t remove the zoom image overlay when I mouseout, and the image stucks in when I step to another image or close the Shutter. I tried the empty(), and remove() methods in jQuery, but none worked well, destroying the complete zoom-script’s functioning.

this is the script:

jQuery("img#shTopImg").live('mouseover mouseout', function(event) {

  if (event.type == 'mouseover') {
var imw = jQuery("img#shTopImg").width();
jQuery(this).delay(200).addimagezoom({
magnifiersize:[350, 350], zoomrange: [3, 8], rightoffset: - imw });
  } else {

// remove logic goes here

}

});

and this is the page where it is: https://baksagaspar.com/MH-work/collections/jungle-under-construction-2

You can see when it opens an image in a shutter, and you navigate to some other picture, it’s zoom overlay still stays on the screen

Any help please how could I solve this problem??
