 * The blog I am managing had some images up to 10MB on the server, i pulled a good
   hundred of them and compressed and optimized them for web. Will this plugin affect
   those images I already edited and make the quality even worse?

 * The plugin keeps track of images that it has compressed, but if you have already
   compressed the images manually then the plugin will not know this.
 * However, if you send an already compressed image via the plugin to our API, it
   will compress less than if you send the original since it tries to balance between
   quality and size. We recommend to only send original files through to our service.
 * By default the plugin will only compress new images uploaded to your media library.
   You can choose yourself if you want to compress the already uploaded images.
