INTRODUCTION

The Image Optimize module provides a framework for image optimization.

It provides a system of 'pipelines' and each pipeline contains 'processors'.

To optimize an image they are passed to a pipeline which orchestrates each processor applying itself to the image.

For example, you may have one pipeline for loss-less optimization that removes unnecessary metadata from images, and a lossy pipeline that applies re-compression via a third party webservice.

Built in support is provided for Drupal image styles, after the usual image style has been applied the derivative image is passed into a configurable pipeline for optimization.
