react-images-zoom-loop

React Images Extended

A simple, responsive lightbox React JS component for displaying an array of images with zooming and rotating capabilities. This is a fork of jossmac/react-images and simokhalil/react-images-extended

Why this fork?

Fork is based on xiaoman885 react-images-zoom repository. I needed it to add additional stuff and make some small fixes for zoom and rotate features. There is also "loop" prop added. If enabled, it prevents arrow images from being hidden on last/first image.

Quick start

npm install --save react-images-zoom

or

yarn add react-images-zoom

import React from 'react';
import Lightbox from 'react-images-zoom';

export default class Sample extends React.Component {
  ...
  render() {
    return (
      <Lightbox
        images={[{ src: 'http://example.com/img1.jpg' }, { src: 'http://example.com/img2.jpg' }]}
        isOpen={this.state.lightboxIsOpen}
        loop
        onClickPrev={this.gotoPrevious}
        onClickNext={this.gotoNext}
        onClose={this.closeLightbox}
        rotatable={true}
        zoomable={true}
        onSave={(currentImageIndex, params) => console.log('currentImageIndex, currentImageSrc, params : ', currentImageIndex, this.props.images[currentImageIndex].src, params)}
      />
    );
  }
}

Loop example

To add a loop to your lightbox gallery you need to add a loop prop to your component and tell lightbox what to do when condition is met. Like:

gotoPrevious() {
    this.setState({
      currentImage: this.state.currentImage - 1,
    });
    if (this.state.currentImage === 0) {
      this.setState({
        currentImage: this.props.images.length - 1,
      });
    }
  }
  gotoNext() {
    this.setState({
      currentImage: this.state.currentImage + 1,
    });
    if (this.state.currentImage === this.props.images.length - 1) {
      this.setState({
        currentImage: 0,
      });
    }
  }

Examples

To build the examples locally, run:

yarn install
yarn start

Then open localhost:8000 in a browser.

Using srcSet

Example using srcSet:

<Lightbox
  images={LIGHTBOX_IMAGE_SET}
  ...
/>

const LIGHTBOX_IMAGE_SET = [
  {
    src: 'http://example.com/example/img1.jpg',
    caption: 'A forest'
    srcSet: [
      'http://example.com/example/img1_1024.jpg 1024w',
      'http://example.com/example/img1_800.jpg 800w',
      'http://example.com/example/img1_500.jpg 500w',
      'http://example.com/example/img1_320.jpg 320w',
    ],
  },
  {
    src: 'http://example.com/example/img2.jpg',
    srcSet: [
      'http://example.com/example/img2_1024.jpg 1024w',
      'http://example.com/example/img2_800.jpg 800w',
      'http://example.com/example/img2_500.jpg 500w',
      'http://example.com/example/img2_320.jpg 320w',
    ],
  }
];
