An AngularJS directive to work with Scott Jehl's Picturefill plugin for responsive images.

This directive works with dynamic content populated by the $scope.

See the demo here.

You can download and install into your project using Bower:

bower install angular-picturefill --save
grunt bower-install

1. Download and install with Bower or manually include this directive and Picturefill in your HTML.
2. Add ng.picturefill as an app dependency.
3. Use the picture-fill directive in your view.
4. Implement Picturefill as usual. Below is an example implementation but you can specify as many options as you like. The only difference is that data-src must be pf-src to avoid conflict.
5. Use the provided trimExt filter on all URLs to remove the file extension so that you can append your custom image sizes. Don't forget to put it back.

Note: All images must share the same file extension for this directive to work properly and all file sizes must be available for each file.

<span picture-fill data-alt="Juicy hanger steak on a croissant.">
  <span pf-src="images/sizes/steak-croissant.png"></span>
  <span pf-src="images/sizes/steak-croissant-100.png" data-media="(min-width: 1px)"></span>
  <span pf-src="images/sizes/steak-croissant-300.png" data-media="(min-width: 400px)"></span>
  <span pf-src="images/sizes/steak-croissant-600.png" data-media="(min-width: 645px)"></span>
  <span pf-src="images/sizes/steak-croissant-1024.png" data-media="(min-width: 960px)"></span>
  <span pf-src="images/sizes/steak-croissant.png" data-media="(min-width: 1200px)"></span>
</span>

The filter trimExt is provided for working with $scope data.

<span picture-fill data-alt="{{post.thumbnail.description}}" ng-if="post.thumbnail">
  <span pf-src="{{post.thumbnail.url}}"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}-150x150.jpg" data-media="(min-width: 1px)"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}-300x300.jpg" data-media="(min-width: 1px) and (-webkit-min-device-pixel-ratio: 1.5),(min-resolution: 144dpi),(min-resolution: 1.5dppx)"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}-300x225.jpg" data-media="(min-width: 320px)"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}-600x450.jpg" data-media="(min-width: 320px) and (-webkit-min-device-pixel-ratio: 1.5),(min-resolution: 144dpi),(min-resolution: 1.5dppx)"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}-1024x768.jpg" data-media="(min-width: 645px)"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}.jpg" data-media="(min-width: 645px) and (-webkit-min-device-pixel-ratio: 1.5),(min-resolution: 144dpi),(min-resolution: 1.5dppx)"></span>
  <span pf-src="{{post.thumbnail.url | trimExt}}.jpg" data-media="(min-width: 2068px)"></span>
</span>

In the future I would like to implement the following:

• Not requiring all images to have the same file extension
