Great plugin and great feedback from developer

Ran into a small bug that accidentally made my API key change. Contacted the developer and they got back to me without 24 hours, reversing my API key to the original one and making a suggestion I made a reality.

As of plugin itself, it does what it needs to do. I am using paid version across almost 100 sites and it does a great job on optimizing images. Used free version originally, but ran out of images allowed super quick. Get paid version if you running a business, you will be happy.
