+
+[imagesloaded.desandro.com](http://imagesloaded.desandro.com)
+
+Detect when images have been loaded.
+
+## Install
+
+### Download
+
++ [imagesloaded.pkgd.min.js](https://unpkg.com/imagesloaded@4/imagesloaded.pkgd.min.js) minified
++ [imagesloaded.pkgd.js](https://unpkg.com/imagesloaded@4/imagesloaded.pkgd.js) un-minified
+
+### CDN
+
+``` html
+<script src="https://unpkg.com/imagesloaded@4/imagesloaded.pkgd.min.js"></script>
+<!-- or -->
+<script src="https://unpkg.com/imagesloaded@4/imagesloaded.pkgd.js"></script>
+```
+
+### Package managers
+
+Install via [npm](https://www.npmjs.com/package/imagesloaded): `npm install imagesloaded`
+
+Install via [Bower](http://bower.io): `bower install imagesloaded --save`
+
+## jQuery
+
+You can use imagesLoaded as a jQuery Plugin.
+
+``` js
+$('#container').imagesLoaded( function() {
+  // images have loaded
+});
+
+// options
+$('#container').imagesLoaded( {
+  // options...
+  },
+  function() {
+    // images have loaded
+  }
+);
+```
+
+`.imagesLoaded()` returns a [jQuery Deferred object](http://api.jquery.com/category/deferred-object/). This allows you to use `.always()`, `.done()`, `.fail()` and `.progress()`.
+
+``` js
+$('#container').imagesLoaded()
+  .always( function( instance ) {
+    console.log('all images loaded');
+  })
+  .done( function( instance ) {
+    console.log('all images successfully loaded');
+  })
+  .fail( function() {
+    console.log('all images loaded, at least one is broken');
+  })
+  .progress( function( instance, image ) {
+    var result = image.isLoaded ? 'loaded' : 'broken';
+    console.log( 'image is ' + result + ' for ' + image.img.src );
+  });
+```
+
+## Vanilla JavaScript
+
+You can use imagesLoaded with vanilla JS.
+
+``` js
+imagesLoaded( elem, callback )
+// options
+imagesLoaded( elem, options, callback )
+// you can use `new` if you like
+new imagesLoaded( elem, callback )
+```
+
++ `elem` _Element, NodeList, Array, or Selector String_
++ `options` _Object_
++ `callback` _Function_ - function triggered after all images have been loaded
+
+Using a callback function is the same as binding it to the `always` event (see below).
+
+``` js
+// element
+imagesLoaded( document.querySelector('#container'), function( instance ) {
+  console.log('all images are loaded');
+});
+// selector string
+imagesLoaded( '#container', function() {...});
+// multiple elements
+var posts = document.querySelectorAll('.post');
+imagesLoaded( posts, function() {...});
+```
+
+Bind events with vanilla JS with .on(), .off(), and .once() methods.
+
+``` js
+var imgLoad = imagesLoaded( elem );
+function onAlways( instance ) {
+  console.log('all images are loaded');
+}
+// bind with .on()
+imgLoad.on( 'always', onAlways );
+// unbind with .off()
+imgLoad.off( 'always', onAlways );
+```
+
+## Background
+
+Detect when background images have loaded, in addition to `<img>`s.
+
+Set `{ background: true }` to detect when the element's background image has loaded.
+
+``` js
+// jQuery
+$('#container').imagesLoaded( { background: true }, function() {
+  console.log('#container background image loaded');
+});
+
+// vanilla JS
+imagesLoaded( '#container', { background: true }, function() {
+  console.log('#container background image loaded');
+});
+```
+
+[See jQuery demo](http://codepen.io/desandro/pen/pjVMPB) or [vanilla JS demo](http://codepen.io/desandro/pen/avKooW) on CodePen.
+
+Set to a selector string like `{ background: '.item' }` to detect when the background images of child elements have loaded.
+
+``` js
+// jQuery
+$('#container').imagesLoaded( { background: '.item' }, function() {
+  console.log('all .item background images loaded');
+});
+
+// vanilla JS
+imagesLoaded( '#container', { background: '.item' }, function() {
+  console.log('all .item background images loaded');
+});
+```
+
+[See jQuery demo](http://codepen.io/desandro/pen/avKoZL) or [vanilla JS demo](http://codepen.io/desandro/pen/vNrBGz) on CodePen.
+
+## Events
+
+### always
+
+``` js
+// jQuery
+$('#container').imagesLoaded().always( function( instance ) {
+  console.log('ALWAYS - all images have been loaded');
+});
+
+// vanilla JS
+imgLoad.on( 'always', function( instance ) {
+  console.log('ALWAYS - all images have been loaded');
+});
+```
+
+Triggered after all images have been either loaded or confirmed broken.
+
++ `instance` _imagesLoaded_ - the imagesLoaded instance
+
+### done
+
+``` js
+// jQuery
+$('#container').imagesLoaded().done( function( instance ) {
+  console.log('DONE  - all images have been successfully loaded');
+});
+
+// vanilla JS
+imgLoad.on( 'done', function( instance ) {
+  console.log('DONE  - all images have been successfully loaded');
+});
+```
+
+Triggered after all images have successfully loaded without any broken images.
+
+### fail
+
+``` js
+$('#container').imagesLoaded().fail( function( instance ) {
+  console.log('FAIL - all images loaded, at least one is broken');
+});
+
+// vanilla JS
+imgLoad.on( 'fail', function( instance ) {
+  console.log('FAIL - all images loaded, at least one is broken');
+});
+```
+
+Triggered after all images have been loaded with at least one broken image.
+
+### progress
+
+``` js
+imgLoad.on( 'progress', function( instance, image ) {
+  var result = image.isLoaded ? 'loaded' : 'broken';
+  console.log( 'image is ' + result + ' for ' + image.img.src );
+});
+```
+
+Triggered after each image has been loaded.
+
++ `instance` _imagesLoaded_ - the imagesLoaded instance
++ `image` _LoadingImage_ - the LoadingImage instance of the loaded image
+
+<!-- sponsored -->
+
+## Properties
+
+### LoadingImage.img
+
+_Image_ - The `img` element
+
+### LoadingImage.isLoaded
+
+_Boolean_ - `true` when the image has successfully loaded
+
+### imagesLoaded.images
+
+Array of _LoadingImage_ instances for each image detected
+
+``` js
+var imgLoad = imagesLoaded('#container');
+imgLoad.on( 'always', function() {
+  console.log( imgLoad.images.length + ' images loaded' );
+  // detect which image is broken
+  for ( var i = 0, len = imgLoad.images.length; i < len; i++ ) {
+    var image = imgLoad.images[i];
+    var result = image.isLoaded ? 'loaded' : 'broken';
+    console.log( 'image is ' + result + ' for ' + image.img.src );
+  }
+});
+```
+
+## Browserify
+
+imagesLoaded works with [Browserify](http://browserify.org/).
+
+``` bash
+npm install imagesloaded --save
+```
+
+``` js
+var imagesLoaded = require('imagesloaded');
+
+imagesLoaded( elem, function() {...} );
+```
+
+Use `.makeJQueryPlugin` to make to use `.imagesLoaded()` jQuery plugin.
+
+``` js
+var $ = require('jquery');
+var imagesLoaded = require('imagesloaded');
+
+// provide jQuery argument
+imagesLoaded.makeJQueryPlugin( $ );
+// now use .imagesLoaded() jQuery plugin
+$('#container').imagesLoaded( function() {...});
+```
+
+## Webpack
+
+Install imagesLoaded with npm.
+
+``` bash
+npm install imagesloaded
+```
+
+You can then `require('imagesloaded')`.
+
+``` js
+// main.js
+var imagesLoaded = require('imagesloaded');
+
+imagesLoaded( '#container', function() {
+  // images have loaded
+});
+```
+
+Use `.makeJQueryPlugin` to make `.imagesLoaded()` jQuery plugin.
+
+``` js
+// main.js
+var imagesLoaded = require('imagesloaded');
+var $ = require('jquery');
+
+// provide jQuery argument
+imagesLoaded.makeJQueryPlugin( $ );
+// now use .imagesLoaded() jQuery plugin
+$('#container').imagesLoaded( function() {...});
+```
+
+Run webpack.
+
+``` bash
+webpack main.js bundle.js
+```
+
+## RequireJS
+
+imagesLoaded works with [RequireJS](http://requirejs.org).
+
+You can require [imagesloaded.pkgd.js](http://imagesloaded.desandro.com/imagesloaded.pkgd.js).
+
+``` js
+requirejs( [
+  'path/to/imagesloaded.pkgd.js',
+], function( imagesLoaded ) {
+  imagesLoaded( '#container', function() { ... });
+});
+```
+
+Use `.makeJQueryPlugin` to make `.imagesLoaded()` jQuery plugin.
+
+``` js
+requirejs( [
+  'jquery',
+  'path/to/imagesloaded.pkgd.js',
+], function( $, imagesLoaded ) {
+  // provide jQuery argument
+  imagesLoaded.makeJQueryPlugin( $ );
+  // now use .imagesLoaded() jQuery plugin
+  $('#container').imagesLoaded( function() {...});
+});
+```
+
+You can manage dependencies with [Bower](http://bower.io). Set `baseUrl` to `bower_components` and set a path config for all your application code.
+
+``` js
+requirejs.config({
+  baseUrl: 'bower_components/',
+  paths: { // path to your app
+    app: '../'
+  }
+});
+
+requirejs( [
+  'imagesloaded/imagesloaded',
+  'app/my-component.js'
+], function( imagesLoaded, myComp ) {
+  imagesLoaded( '#container', function() { ... });
+});
+```
+
+## Browser support
+
++ IE9+
++ Android 2.3+
++ iOS Safari 4+
++ All other modern browsers
+
+Use [imagesLoaded v3](http://imagesloaded.desandro.com/v3/) for IE8 support.
+
+## MIT License
+
+imagesLoaded is released under the [MIT License](http://desandro.mit-license.org/). Have at it.

+## Submitting issues
+
+### Reduced test case required
+
+All bug reports and problem issues require a [**reduced test case**](http://css-tricks.com/reduced-test-cases/).
+
++ A reduced test case clearly demonstrates the bug or issue.
++ It contains the bare minimum HTML, CSS, and JavaScript required to demonstrate the bug.
++ A link to your production site is **not** a reduced test case.
+
+Create a test case by forking a [CodePen demos](http://codepen.io/desandro/pens/tags/?selected_tag=imagesloaded-docs).
+
++ [progress with jQuery](http://codepen.io/desandro/pen/bIFyl)
++ [progress with vanilla JS](http://codepen.io/desandro/pen/hlzaw)
++ [`{ background: true }` with jQuery](http://codepen.io/desandro/pen/pjVMPB)
++ [`{ background: true }` with vanilla JS](http://codepen.io/desandro/pen/avKooW)
++ [`{ background: '.selector' }` with jQuery](http://codepen.io/desandro/pen/avKoZL)
++ [`{ background: '.selector' }` with vanilla JS](http://codepen.io/desandro/pen/vNrBGz)
+
+Providing a reduced test case is the best way to get your issue addressed. They help you point out the problem. They help me verify and debug the problem. They help others understand the problem. Without a reduced test case, your issue may be closed.
