Fix Zoom Image Bug Which Prevents To Go Back To Previous Images

At your theme edit code window, find file 'bc.script.js.liquid'.  

Next, find function 'refreshZoom' (refer to image below)

Add the following piece of code right after the code in that image:

jQuery('.thumb-img').click(function(){
        $('.zoomContainer').remove();
        zoomImage.removeData('elevateZoom');

        zoomImage.attr('src', $(this).data('image'));
        zoomImage.data('zoom-image', $(this).data('zoom-image'));

       COPY THE WHOLE CODE FROM 'zoomImage.elevateZoom({...})' THAT YOU CAN SEE IN YOUR CODE TO THIS SECTION
  })
