Therefore, this lightbox popup image works well with photo galleries. So we can call it Gallery Images Lightbox modal box. Hence, if you already have a gallery then on your webpage then you can still implement this plugin. It gives you simple image popup functionality with different customization options.

How to Use OnClick Image Popup jQuery Lightbox

The implementation is very simple and can start by adding the main jquery file into the header. You can load the JQuery Javascript library into the webpage as follow:

<!-- jQuery -->
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>

After that, we will load the plugin assets and it includes a stylesheet and popup file into the web project just like given below.

<!-- Image Popup CSS -->
<link rel="stylesheet" href="css/style.css">
<!-- Image Popup JS -->
<script src="js/jquery.image-popup.js"></script>

We are in a position to create the HTML content for the gallery so we can apply the popup on the images. So we will create the gallery by defining the ul and li unorder item list. Then we will place an image instead of each of the li.

<ul id="imageGallery">
    <a><img src="img/img1.jpg" alt="Sample Image 1"></a>
    <a><img src="img/img2.jpg" alt="Sample Image 2"></a>
    <a><img src="img/img3.jpg" alt="Sample Image 3"></a>
    <a><img src="img/img4.jpg" alt="Sample Image 4"></a>
    <a><img src="img/img5.jpg" alt="Sample Image 5"></a>

In order to make work the image popup lightbox on each image, we will start our Javascript code by defining the jQuery document ready function. Then we will call the #imageGallery to activate the overly on all the images inside in it.

    //overlay: "rgba(0, 100, 0, 0.5)"

        src: "images/close.png",
        width: "40px",
    imageBorder: "15px solid #ffffff",
    borderRadius: "10px",
    imageWidth: "500px",
    imageHeight: "400px",
    imageCaption: {
        exist: true,
        color: "#ffffff",
        fontSize: "40px"
    open: function(){
    close: function(){
