...

Create the HTML for the 360-degree image viewer and add the first product image like these:

<div class="container" id="pdtViewer">
  <div id="loader">
      <div class="three-bounce">
          <div class="one"></div>
          <div class="two"></div>
          <div class="three"></div>
      </div>
  </div>
  <img src="./img/1.png" id="car" />
  <button class="prev">&laquo;</button>
  <button class="nxt">&raquo;</button>
</div>
<div id="dummy"></div>

  margin: 0 auto;
  border: 0.5px solid #eee;
}
#pdtViewer img { padding: 40px 20px; }
 @media screen and (max-width:1250px) {
#pdtViewer img { width: 100%; }
}
#pdtViewer .nxt { left: 85%; }
#pdtViewer .prev { left: 12%; }
#pdtViewer button {

The core JavaScript to activate the 360-degree image viewer.

window.addEventListener("load", function () {
  document.querySelector('#loader').style.display = 'none';
});
//pdt360DegViewer(imgid, count, path, imgType, keyNavigation);
pdt360DegViewer('car', 51, './img/', 'png', true);
function pdt360DegViewer(id, n, p, t, keys) {
  var i = 1, j = 0, move = [],
  img = document.querySelector(`#${id}`);
  for (var k = 1; k <= n; k++) {
      document.getElementById('dummy').innerHTML += `<img src="./img/${k}.png">`
  }
  img.addEventListener('mousemove', function (e) {
      j++;
      var coord = (e.clientX - img.offsetLeft);
      move.push(coord);
      var l = move.length,
          oldMove = move[l - 2],
          newMove = move[l - 1];
      if (!(j % 3)) {
          if (newMove > oldMove)
              nxt(this);
          else if (newMove < oldMove)
              prev(this);
      }
  });
  img.addEventListener('mouseleave', function () {
      move = [];
  });
  function prev(e) {
      if (i <= 1) {
          i = n;
          e.src = `${p}${--i}.${t}`;
          nxt(e);
      } else
          e.src = `${p}${--i}.${t}`;
  }
  function nxt(e) {
      if (i >= n) {
          i = 1;
          e.src = `${p}${++i}.${t}`;
          prev(e);
      } else
          e.src = `${p}${++i}.${t}`;
  }
  var prevBtn = document.querySelectorAll('.prev');
  for (var i = 0; i < prevBtn.length; i++) {
      prevBtn[i].addEventListener('click', function () {
          prev(this.parentNode.querySelector('img'));
      });
  }
  var nxtBtn = document.querySelectorAll('.nxt');
  for (var i = 0; i < nxtBtn.length; i++) {
      nxtBtn[i].addEventListener('click', function () {
          nxt(this.parentNode.querySelector('img'));
      });
  }
  if (keys) {
      window.onkeydown = function (e) {
          if (e.keyCode == 37)
              prev(img);
          else if (e.keyCode == 39)
              nxt(img);
      };
  }
}
