This example demonstrates the basic usage of the image API.
This module demonstrates the use of image styles and effects, including the following topics.
- Demonstrate how a module can add additional effects to the options available when creating image styles.
- Demonstrate the usage of hook_image_styles_alter() to modify existing image effects without having to override the styles.
- Demonstrate the usage of hook_image_style_save() and hook_image_style_delete() to update module specific variables when an image style is either re-named or deleted.
- Generate a form with a #managed_file field which allows users to upload an image and choose a style to display that image.
- Demonstrate the usage of theme_image_style() to display images using an image style.
