Disable Responsive Images Complete

Light as feather and fixed our problem of WordPress "helping" us by serving an unoptimised, resized version of a PNG image that was 4x the size of the original. You'd think they'd just not add it if was larger.

Ace.

We had a client site that kept claiming their images were blurry. I was unable to duplicate it, but I figured it was due to the responsive images being output. I activated the plugin and could immediately spot the culprit. I figured there was a plugin with a reputable author that had a solution for this, so thank you so much for developing it.

Works Perfect

Completely disables WP responsive images.

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

Very simple plugin to get retina images on your WordPress site. Automatically load high resoloution images using the new srcset attribute.
