[DEMO](https://frontend-collective.github.io/react-image-lightbox/) Features - Keyboard shortcuts (with rate limiting) - Image Zoom - Flexible rendering using src values assigned on the fly - Image preloading for smoother viewing - Mobile friendly, with pinch to zoom and swipe (Thanks, [@webcarrot](https://github.com/webcarrot)!) ## Example ```jsx import React, { Component } from 'react'; import Lightbox from 'react-image-lightbox'; import 'react-image-lightbox/style.css'; // This only needs to be imported once in your app const images = [ '//placekitten.com/1500/500', '//placekitten.com/4000/3000', '//placekitten.com/800/1200', '//placekitten.com/1500/1500', ]; export default class LightboxExample extends Component { constructor(props) { super(props); this.state = { photoIndex: 0, isOpen: false, }; } render() { const { photoIndex, isOpen } = this.state; return (

{isOpen && ( this.setState({ isOpen: false })} onMovePrevRequest={() => this.setState({ photoIndex: (photoIndex + images.length - 1) % images.length, }) } onMoveNextRequest={() => this.setState({ photoIndex: (photoIndex + 1) % images.length, }) } /> )}

); } } ``` Play with the code on the [example on CodeSandbox](https://codesandbox.io/s/l9n3vnz8yz) ## Options | Property | Type | Description | | :------------------------------ | :----: | :------------------------------------------------------------------------------------------------------------------------------------------------------------ | | mainSrc

Should change the parent state such that `props.prevSrc` becomes `props.mainSrc`, `props.mainSrc` becomes `props.nextSrc`, etc. | | onMoveNextRequest | func | Move to next image event. Should change the parent state such that `props.nextSrc` becomes `props.mainSrc`, `props.mainSrc` becomes `props.prevSrc`, etc. | | onImageLoad | func | Called when an image loads.
