Perfect Image Optimizer Plugin

This plugin does exactly what it has to do no more or less and that is optimizing images. No added useless bells and whistles that are conflicting with the performance or other plugins.

* I tested it in a multi site WP environment => works perfect!
* I added pictures directly via FTP and used an ‘add from server’ plugin. While that plugin was adding the pictures to the WP media folder this ‘EWWW image optimizer’ plugin optimized the images directly in the background without any action/input required from my side => works perfect!
* I then removed a picture from the WP media folder and checked via FTP if it leaves behind any resized picture as trash on the server, but I was astonished that it deleted all the resized formats of the picture => works perfect!
