NCC Image Checker

Seems usefull tool for our QA who test retina support. Update: Great app! Correctly supports testing Retina emulation.

Easy to use extension to quickly identify where your content team haven't followed your web performance budgets.

Class little tool this, really quick way to see if your serving the right size images to your customers and impacting your site's performance..

I find myself using this much more than I expected. A great way to quickly see what might be making a webpage slow to load!

A really useful tool to quickly see if my images are unoptimised and causing me pain. (or to see how bad others are at optimising images!!)
