Image Manager (IM) automates image and video processing and offloads the creation of derivative images in various sizes and formats to the CDN. When an end user requests an image, IM dynamically selects the optimal derivative image.
With Image Manager policies, you can control which derivative image IM serves. Policies also offer a suite of transformations, such as cropping, rotation, color adjustment, and watermarking.
