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.
