I have a button in my wordpress website that popup a gallery, my problem is that the gallery is loading the image from the code, so when my clients need to upload a new image I need to add it for him in the code. How can I make it?
Here is the code:
<!DOCTYPE html>
<html>
<body>
<img class="alignnone size-full wp-image-133 aligncenter" style="border: 5px solid white; border-radius: 50%; background: white; box-shadow: 1px 1px 5px gray;" src="https://upload.wikimedia.org/wikipedia/commons/thumb/c/c2/F_icon.svg/2000px-F_icon.svg.png" alt="" width="72" height="72" onclick="openModal();currentSlide(1)" class="hover-shadow cursor"><strong>try</strong>
</div>
</div>
<div id="myModal" class="modal">
<span class="close cursor" onclick="closeModal()">×</span>
<div class="modal-content">
<div class="mySlides">
<div class="numbertext">1 / 4</div>
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/c/c2/F_icon.svg/2000px-F_icon.svg.png" style="width:100%">
</div>
<div class="mySlides">
<div class="numbertext">2 / 4</div>
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/c/c2/F_icon.svg/2000px-F_icon.svg.png" style="width:100%">
</div>
<div class="mySlides">
<div class="numbertext">3 / 4</div>
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/c/c2/F_icon.svg/2000px-F_icon.svg.png" style="width:100%">
</div>
<div class="mySlides">
<div class="numbertext">4 / 4</div>
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/c/c2/F_icon.svg/2000px-F_icon.svg.png" alt="Nature and sunrise" style="width:100%">
</div>
<a class="prev" onclick="plusSlides(-1)">❮</a>
<a class="next" onclick="plusSlides(1)">❯</a>
<div class="caption-container">
<p id="caption"></p>
</div>
<script>
function openModal() {
document.getElementById('myModal').style.display = "block";
}
function closeModal() {
document.getElementById('myModal').style.display = "none";
}
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("demo");
var captionText = document.getElementById("caption");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
captionText.innerHTML = dots[slideIndex-1].alt;
}
</script>
</body>
</html>
