Enables shortcode and a template tag to pull srcset-images by attachment-ID. This is way to complement WordPress built in srcset which (of course) focus on the_content images and media-sizes set in settings. Sometimes your layout demands more, or you are using other ways to put images on your site not using the_thumbnail or the_content. For example, I use Advanced Custom Fields a lot pulling images by ID.
Generated markup are built from a set of custom image-sizes and the, by you configured, (srcset-)sizes attribute. Use the settings-page for default values and override them any time in the shortcode or template tag.

<li>Option: Enable simple lightbox functionality. </li>
<li>Option: Enable lazhyloading. Option: Include Picturefill</li>
</ul>

The new srcset attribute has recently dropped in Chrome and Firefox. It is the simplest way to get retina ready images on your site.
This plugin will automatically add the srcset attribute to your images if a suitable retina sized image can be found.
It also includes a JS polyfill – <a href="https://github.com/scottjehl/picturefill" rel="nofollow ugc">Picturefill</a> – to ensure that this works on all browsers – not just those that support srcset. This is about 6.5kb, and can easily be dequeued if you only wish to support browsers that have implemented this functionality.
This plugin does not handle generation of the alternative images, and this should either be done manually or using another plugin. See installation instructions for more information.
This plugin requires PHP 5.3

WP Srcset
