 * Hi. Looks like a great plugin and well recommended. However it does not automatically
   install optipng, which is essential for optimizing png files – of which I have
   many. THE PROBLEM IS that it has been impossible to find a coherent explanation
   of how to install optipng given that it has not installed automatically. Time
   is too short, and there are many plugins, so next please!
