 * Hi
 * I am wondering how the plugin works.
 * Does it use the WordPress database to determine the media files to compress or
   does it scan the uploads folder for media files to compress?
 * Thanks
 * John

 * Hi John,
 * I hope you are well today and thank you for your question.
 * This WP smush.it plugin is a simple bridge between WordPress and [Yahoo’s smush.it API](http://www.smushit.com/ysmush.it/),
   It smushes the images by calling Yahoo’s smush.it APIs.
 * The Smush.it uses optimization techniques specific to image format to remove 
   unnecessary bytes from image files. It is a “lossless” tool, which means it optimizes
   the images without changing their look or visual quality.
 * It doesn’t compress the images files but just removes unnecessary bytes from 
   image file which results in reducing image file size.
 * You will find more information about it on the following page.
