Images Module

The image plugin is an extension to the storage plugin that identifies images and provides thumbnails as well as resizing of the original image.

Image Module

The Image_Module type represents the image module. An instance of the image module must be declared and registered when the application is created and initialized. The image module is associated with the image service which provides and implements the image management operations.

When the image module is initialized, it registers itself as a listener to the storage module to be notified when a storage file is created, updated or removed. When a file is added, it looks at the file type and extracts the image information if the storage file is an image.
