Each time window resizes, the append method keeps adding to container

I'm trying to switch out my images in Bootstrap's carousel at the 768px breakpoint only for responsive purposes. So I decided to use the resize() method and append the smaller images to the .carousel-inner div when they reach equal to or less than to 768px or maintain large images if window is larger than 768. However, when ever I resize the window it keeps appending those images over and over again until I stop resizing. Only returns to normal when I refresh. Which this all makes sense that it the code executes every time the window gets resized. So I was wondering if there is a method out there that I should be trying instead? I kind want it to act like a media query... I have pasted my code below and you can check it out on my GitHub: https://ldgoncalves.github.io/ChamberStat/html/index.html

I'm using Laravel 5.3 for this as well.

$(window).on("resize load", function () {
if ($(window).width() <= 768) {

var smallerImg = '<div class="item active"><img src="{{asset('images/slide4.png')}}" alt="First slide of a customer review"></div>' +
'<div class="item"><img src="{{asset('images/slide5.png')}}" alt="Second slide of a customer review"></div>' +
'<div class="item"><img src="{{asset('images/slide6.png')}}" alt="Third slide of a customer review"></div>'+
'<div class="item"><img src="{{asset('images/slide7.png')}}" alt="Fourth slide of a customer review"></div>'+
'<div class="item"><img src="{{asset('images/slide8.png')}}" alt="Fifth slide of a customer review"></div>'+
'<div class="item"><img src="{{asset('images/slide9.png')}}" alt="Sixth slide of a customer review"></div>';
var largerImg = '<div class="item active"><img src="{{asset('images/slide1.png')}}" alt="First slide of customer reviews"></div>' +
'<div class="item"><img src="{{asset('images/slide2.png')}}" alt="Second slide of customer reviews"></div>' +
'<div class="item"><img src="{{asset('images/slide3.png')}}" alt="Third slide of customer reviews"></div>';

You only want the content change to happen when the mode changes. And you probably want to empty() the list when changing content. Something like this:

$(window).on("resize load", function () {
  var largerImg = '...';
  var smallerImg = '...';
  var $carousel = $('.carousel-inner');
  var lastMode = $carousel.hasClass('small') ? 'small' : 'large';
  var newMode = $(window).width()  <= 768 ? 'small' : 'large';

  if (lastMode === newMode)

  if (newMode === 'small') {
  } else{
