The best image optimiser plugin

I just love this plugin.
It does a brilliant job at optimising images but also is pain-free when installing it for clients allowing you to create an account for the client within the plugin settings. No getting client to confirm the account. Install the plugin, add client email, Done. The API key is immediately installed.
It just runs effortlessly in the background.
They have a generous pricing structure and you can stack your accounts plus create sub-accounts which is a very nice option. Big fan – support is awesome and this plugin rocks. We put it on all our websites.
