Clickable image slideshow

Hi @zreames ,

I don't have the above HTML file.

But you can implement the Slideshow  using below HTML code :

<style>* {
  box-sizing: border-box;
}

/* Position the image container (needed to position the left and right arrows) */
.container {
  position: relative;
}

/* Hide the images by default */
.mySlides {
  display: none;
}

/* Add a pointer when hovering over the thumbnail images */
.cursor {
  cursor: pointer;
}

/* Next & previous buttons */
.prev,
.next {
  cursor: pointer;
  position: absolute;
  top: 40%;
  width: auto;
  padding: 16px;
  margin-top: -50px;
  color: white;
  font-weight: bold;
  font-size: 20px;
  border-radius: 0 3px 3px 0;
  user-select: none;
  -webkit-user-select: none;
}

/* Position the "next button" to the right */
.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

/* On hover, add a black background color with a little bit see-through */
.prev:hover,
.next:hover {
  background-color: rgba(0, 0, 0, 0.8);
}

/* Number text (1/3 etc) */
.numbertext {
  color: #f2f2f2;
  font-size: 12px;
  padding: 8px 12px;
  position: absolute;
  top: 0;
}

/* Container for image text */
.caption-container {
  text-align: center;
  background-color: #222;
  padding: 2px 16px;
  color: white;
}

.row:after {
  content: "";
  display: table;
  clear: both;
}

/* Six columns side by side */
.column {
  float: left;
  width: 16.66%;
}

/* Add a transparency effect for thumnbail images */
.demo {
  opacity: 0.6;
}

.active,
.demo:hover {
  opacity: 1;
}</style>

Just copy those in HTML(<>) tabs and replace them with link of your image files.

and add below JS to your question:

Qualtrics.SurveyEngine.addOnload(function()
{
	/*Place your JavaScript here to run when the page loads*/

});

Qualtrics.SurveyEngine.addOnReady(function()
{
	// Get the elements
var prevBtn = document.querySelector(".prev");
var nextBtn = document.querySelector(".next");
var slides = document.querySelectorAll(".mySlides");
var dots = document.querySelectorAll(".demo");

// Set the initial slide index
var slideIndex = 1;
showSlides(slideIndex);

// Function to move to the next slide
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Function to show a specific slide
function currentSlide(n) {
  showSlides(slideIndex = n);
}

// Function to display the slides
function showSlides(n) {
  // Reset the index if it exceeds the number of slides
  if (n > slides.length) {
    slideIndex = 1;
  } else if (n < 1) {
    slideIndex = slides.length;
  }

  // Hide all the slides
  for (var i = 0; i < slides.length; i++) {
    slides[i].style.display = "none";
  }

  // Remove the active class from all the dots
  for (var i = 0; i < dots.length; i++) {
    dots[i].className = dots[i].className.replace(" active", "");
  }

  // Display the current slide and add the active class to its corresponding dot
  slides[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " active";
}

// Event listener for the previous and next buttons
prevBtn.addEventListener("click", function() {
  plusSlides(-1);
});

nextBtn.addEventListener("click", function() {
  plusSlides(1);
});

// Event listener for the dots
for (var i = 0; i < dots.length; i++) {
  dots[i].addEventListener("click", function() {
    var slideNumber = parseInt(this.alt.split(" ")[0]);
    currentSlide(slideNumber);
  });
}


});

Qualtrics.SurveyEngine.addOnUnload(function()
{
	/*Place your JavaScript here to run when the page is unloaded*/

});

Hope this resolves your query😊
