Installation

Getting started with React Image Gallery is straightforward. First, ensure that you have React 16.0.0 or later installed in your project. Then, you can install the library using npm or yarn:

npm install react-image-gallery

or

yarn add react-image-gallery

After installation, you’ll need to import the library’s styles. You have several options for doing this:

// Using SCSS
import "react-image-gallery/styles/scss/image-gallery.scss";

// Using CSS
import "react-image-gallery/styles/css/image-gallery.css";

// Using JavaScript (with webpack)
import "react-image-gallery/styles/css/image-gallery.css";

Basic Usage

Let’s start with a simple example to demonstrate how to create a basic image gallery:

import React from 'react';
import ImageGallery from 'react-image-gallery';

const MyGallery: React.FC = () => {
  const images = [
    {
      original: 'https://picsum.photos/id/1018/1000/600/',
      thumbnail: 'https://picsum.photos/id/1018/250/150/',
    },
    {
      original: 'https://picsum.photos/id/1015/1000/600/',
      thumbnail: 'https://picsum.photos/id/1015/250/150/',
    },
    {
      original: 'https://picsum.photos/id/1019/1000/600/',
      thumbnail: 'https://picsum.photos/id/1019/250/150/',
    },
  ];

  return <ImageGallery items={images} />;
};

export default MyGallery;

In this example, we import the ImageGallery component and create an array of image objects. Each object contains an original URL for the full-size image and a thumbnail URL for the preview. The ImageGallery component is then rendered with the items prop set to our array of images.

React Image Gallery offers numerous props to customize its behavior. Here’s an example with some common customizations:

import React from 'react';
import ImageGallery from 'react-image-gallery';

const CustomGallery: React.FC = () => {
  const images = [
    // ... image objects
  ];

  return (
    <ImageGallery
      items={images}
      showPlayButton={false}
      showFullscreenButton={true}
      slideInterval={3000}
      slideOnThumbnailOver={true}
      showIndex={true}
      onSlide={(currentIndex) => {
        console.log(`Slide changed to index ${currentIndex}`);
      }}
    />
  );
};

export default CustomGallery;

This configuration disables the play button, enables fullscreen mode, sets a slide interval of 3 seconds, allows sliding on thumbnail hover, displays the current image index, and logs a message when the slide changes.

Advanced Usage

React Image Gallery’s flexibility allows for more sophisticated implementations and customizations. Let’s explore some advanced features:

Custom Slide Rendering

You can create custom slide layouts by using the renderItem prop:

import React from 'react';
import ImageGallery from 'react-image-gallery';

const AdvancedGallery: React.FC = () => {
  const images = [
    // ... image objects
  ];

  const renderItem = (item: any) => {
    return (
      <div className="custom-slide">
        <img src={item.original} alt={item.originalAlt} />
        <div className="custom-caption">
          <h3>{item.title}</h3>
          <p>{item.description}</p>
        </div>
      </div>
    );
  };

  return <ImageGallery items={images} renderItem={renderItem} />;
};

export default AdvancedGallery;

This example demonstrates how to create a custom slide layout with a caption overlay.

Custom Navigation Controls

React Image Gallery allows you to customize navigation controls. Here’s an example of custom left and right navigation buttons:

import React from 'react';
import ImageGallery from 'react-image-gallery';

const CustomControlsGallery: React.FC = () => {
  const images = [
    // ... image objects
  ];

  const renderLeftNav = (onClick: () => void, disabled: boolean) => (
    <button
      className="custom-left-nav"
      onClick={onClick}
      disabled={disabled}
    >
      Previous
    </button>
  );

  const renderRightNav = (onClick: () => void, disabled: boolean) => (
    <button
      className="custom-right-nav"
      onClick={onClick}
      disabled={disabled}
    >
      Next
    </button>
  );

  return (
    <ImageGallery
      items={images}
      renderLeftNav={renderLeftNav}
      renderRightNav={renderRightNav}
    />
  );
};

export default CustomControlsGallery;

This example replaces the default arrow navigation with custom “Previous” and “Next” buttons.

Responsive Design

React Image Gallery is responsive by default, but you can further customize its behavior for different screen sizes:

import React from 'react';
import ImageGallery from 'react-image-gallery';

const ResponsiveGallery: React.FC = () => {
  const images = [
    // ... image objects
  ];

  return (
    <ImageGallery
      items={images}
      showThumbnails={window.innerWidth > 768}
      thumbnailPosition={window.innerWidth > 1024 ? 'left' : 'bottom'}
    />
  );
};

export default ResponsiveGallery;

This example adjusts the thumbnail visibility and position based on the window width, providing a more optimized experience across different devices.

With its extensive customization options, responsive design, and mobile-friendly features, it’s an excellent choice for developers looking to enhance their projects with rich media displays.
