React Grid Gallery

Justified image gallery component for React inspired by Google Photos and based upon React Images.

📣 Maintainers wanted 📣

As react-grid-gallery continues to gain popularity and provide value to many users (over a million downloads from NPM alone) it requires maintainers to take care of issues and pull requsts, and to progress the software. If you're getting value from using this component or if you're just interested in becoming a maintainer, please let me know.

A very big thankyou to Isaev Igor (@itoldya) for taking on a substantial amount of work in smoothing out some (of the many) rough edges, and for bringing react-grid-gallery up to date. I really appreciate the care taken. Check out his site at picryl.com (a great example of react-grid-gallery in use).

Note:

As of the release of v0.5.4 (2019-03-10) I will no longer be actively adding features and maintaining react-grid-gallery. My online behavioral experiment platform Psychstudio consumes all of my time and I am no longer capable of giving react-grid-gallery the attention it needs. A big thanks to everyone who has contributed over the last 5 years and thanks to everyone who has downloaded react-grid-gallery (hopefully it has been useful to you).

Installation

Using npm:

npm install --save react-grid-gallery

Quick (and dirty) Start

import React from 'react';
import { render } from 'react-dom';

        src: "https://c2.staticflickr.com/9/8817/28973449265_07e3aa5d2e_b.jpg",
        thumbnail: "https://c2.staticflickr.com/9/8817/28973449265_07e3aa5d2e_n.jpg",
        thumbnailWidth: 320,
        thumbnailHeight: 174,
        isSelected: true,
        caption: "After Rain (Jeshu John - designerspics.com)"
},
{
        src: "https://c2.staticflickr.com/9/8356/28897120681_3b2c0f43e0_b.jpg",
        thumbnail: "https://c2.staticflickr.com/9/8356/28897120681_3b2c0f43e0_n.jpg",
        thumbnailWidth: 320,
        thumbnailHeight: 212,
        tags: [{value: "Ocean", title: "Ocean"}, {value: "People", title: "People"}],
        caption: "Boats (Jeshu John - designerspics.com)"

{
        src: "https://c4.staticflickr.com/9/8887/28897124891_98c4fdd82b_b.jpg",
        thumbnail: "https://c4.staticflickr.com/9/8887/28897124891_98c4fdd82b_n.jpg",
        thumbnailWidth: 320,
        thumbnailHeight: 212
}]

render(
        <Gallery images={IMAGES}/>,
        document.getElementById('example-0')
);

Image Options

Property Type Default Description
src string undefined Required. A string referring to any valid image resource (file, url, etc).
thumbnail string undefined Required. A string referring to any valid image resource (file, url, etc).
thumbnailWidth number undefined Required. Width of the thumbnail image.
thumbnailHeight number undefined Required. Height of the thumbnail image.
nano string:base64 undefined Optional. Thumbnail Base64 image will be injected to background under the main image. This provides a base64, 4x4 generated image whilst the image is beong loaded.
alt string "" Optional. Image alt attribute.
tags array undefined Optional. An array of objects containing tag attributes (value, title and key if value is element). e.g. {value: "foo", title: "bar"} or {value: <a href={tag.url}>{tag.name}</a>, title: tag.title, key: tag.key}
isSelected bool undefined Optional. The selected state of the image.
caption string|element undefined Optional. Image caption.
customOverlay element undefined Optional. A custom element to be rendered as a thumbnail overlay on hover.
thumbnailCaption string|element undefined Optional. A thumbnail caption shown below thumbnail.
orientation number undefined Optional. Orientation of the image. Many newer digital cameras (both dSLR and Point & Shoot digicams) have a built-in orientation sensor. The output of this sensor is used to set the EXIF orientation flag in the image file's metatdata to reflect the positioning of the camera with respect to the ground (See EXIF Orientation Page for more info).

Gallery Options

Property Type Default Description
images array undefined Required. An array of objects containing image properties (see Image Options above).
id string "ReactGridGallery" Optional. id attribute for <Gallery> tag. This prop may be useful for those who wish to discriminate between multiple galleries.
enableImageSelection bool true Optional. Allow images to be selectable. Setting this option to false whilst supplying images with isSelected: true will result in those images being permanently selected.
onSelectImage func undefined Optional. Function to execute when an image is selected. Allows access to image object using this (See Programmers notes for more info about implicit this). Optional args: index (index of selected image in images array), image (the selected image). This function is only executable when enableImageSelection: true.
rowHeight number 180 Optional. The height of each row in the gallery.
maxRows number undefined Optional. The maximum number of rows to show in the gallery.
margin number 2 Optional. The margin around each image in the gallery.
onClickThumbnail func undefined Optional. Function to execute when gallery thumbnail clicked. Allows access to image object using this (See Programmers notes for more info about implicit this). Optional args: index (index of selected image in images array), event (the click event).
tagStyle object tagStyle Optional. Style to pass to tag elements. Overrides internal tag style.
tileViewportStyle func tileViewportStyle Optional. Function to style the image tile viewport. Allows access to image object using this (See Programmers notes for more info about implicit this). Overrides internal tileViewportStyle function.
thumbnailStyle func thumbnailStyle Optional. Function to style the image thumbnail. Allows access to image object using this (See Programmers notes for more info about implicit this). Overrides internal thumbnailStyle function.
thumbnailImageComponent React component undefined Optional. Substitute in a React component that would get passed imageProps (the props that would have been passed to the <img> tag) and item (the original item in images) to be used to render thumbnails; useful for lazy loading.
defaultContainerWidth number 0 Optional. Set default width for the container. This option is useful during server-side rendering when we want to generate an initial markup before we can detect the actual container width.

General Notes

  • react-grid-gallery is built for modern browsers and therefore IE support is limited to IE 11 and newer.

  • As the inspiration for this component comes from Google Photos, very small thumbnails may not be the most aesthetically pleasing due to the border size applied when selected. A sensible rowHeight default of 180px has been chosen, but rowHeights down to 100px are still reasonable.

  • Gallery width is determined by the containing element. Therefore your containing element must have a width (%, em, px, whatever) before the gallery is loaded!

  • Image Options: thumbnail can point to the same resource as src, bearing in mind the resultant data size of the gallery and page load cost. Thumbnails of whatever size will be scaled to match rowHeight.

Programmers Notes

  • User defined functions that allow access to this via Function.prototype.call() do not require you to declare or pass this as a parameter. this will be defined at the time the function is called.

e.g.

// somewhere in your code...
function myTileViewportStyleFn() {
  if (this.props.item.isSelected)
    return {
           // something stylish...
            };
}

<Gallery images={IMAGES} tileViewportStyle={myTileViewportStyleFn}/>


// internally, within the react-grid-gallery component it will be called like so:
myTileViewportStyleFn.call(this); // this now refers to the image to be styled
  • If you don't know your thumbnailWidth and thumbnailHeight values, you can find these out using any number of javascript hacks, bearing in mind the load penalty associated with these methods.
