Steps for dynamically loading the content of a Bootstrap 4 Modal

I am currently in the process of developing a website that will showcase a wide range of images. The design is set up as a landing page with all content contained within the main HTML page - there is only an index.html file for now.

This website will serve as the official online platform for a Theater, featuring images related to their various shows. To provide an estimate of the number of images:

There are about 40 shows, each with roughly 40 images per show (approximately 600kb per image).

That's nearly 1gb of pictures on a single page!

Each show is represented by an image, and clicking on the image opens a modal displaying additional related images in a grid format along with information about the show.

I am utilizing Bootstrap 4, jQuery, and CSS for this project.

The issue I am facing is that including all the modals with images directly on the HTML page causes the website to load slowly and not function properly.

I am exploring options to dynamically load images each time a user clicks on a show, rather than loading all pictures at once when the page initially loads.

While I have attempted jQuery injection, managing the opening and closing of modals has proved challenging, making it an inefficient coding method.

One solution I am considering involves manipulating images via a PHP server. PHP can process and optimize images, creating thumbnails to be displayed in the grid format so they do not load in full size until clicked (using lightbox.js). However, my knowledge of PHP is limited, and I have not found a simple tutorial for implementation.

I am open to any suggestions on how to approach this issue, especially those focused on SEO optimization and improving client-side loading speed!

<!-- MODAL EXAMPLE -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-full " data-dismiss="modal">
    <div class="modal-content mx-auto">
      <div class="modal-body">
        <div class="column mx-auto">
          <div class="sidebar-box">
            <h2 class="title">SHOW TITLE</h2>
            <h2 class="subtitle"> SHOW SUBTITLE</h2>
            <p class="middle">MIDDLE INFORMATION</p>
            <p class="description">SHOW DESCRIPTION</p>
          </div>

        </div>
        <div class="column mx-auto">
          <!-- THERE WILL BE ALL THE IMAGES IN A GRID-->
          <div class="row justify-content-center">
            <a href="stages/alesi/alesi1.JPG" data-title="Photography ©" data-lightbox="alesi">
              <img src="stages/alesi/alesi1.JPG" alt="" />
            </a>
            <a href="stages/alesi/alesi2.JPG" data-title="Photography ©" data-lightbox="alesi">
              <img src="stages/alesi/alesi2.JPG" alt="" />
            </a>
            <a href="stages/alesi/alesi3.JPG" data-title="Photography ©" data-lightbox="alesi">
              <img src="stages/alesi/alesi3.JPG" alt="" />
            </a>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

To implement this technique, you can utilize AJAX to load the content of each modal from a separate HTML or PHP file. Upon clicking on the modal, an AJAX request can be made to fetch and display the specific modal content within the page.

In essence, the entire <div class="modal-body"> section will reside in a distinct HTML file. When a modal is clicked, the following script can be executed:

$("the_modal").click(function(){
  $.ajax({url: "modal1.html", success: function(result){
    $("#myModal modal-content").append(result);
  }});
});

Additionally, you have the option to include data attributes on the modal and utilize them during the AJAX call to make it applicable for all modals across the website.

An additional improvement would involve optimizing images by reducing their size and quality.

Are you struggling with slow page loading times due to a large number of images? Consider implementing lazy-loading for your images to improve website performance. With lazy-loading, images will only load when they are visible in the viewport.

You can use a jQuery plugin called jQuery.Lazy() to easily implement lazy-loading on your website.

It is not recommended to load 40 pictures of 600k by default as this may cause issues for mobile users. A better approach would be to utilize a gallery script such as Photo Swipe and implement a server-side script to retrieve a json file that will only create the gallery when requested.
