In previous versions of Drupal, sharing images required many different modules and lots of configuration options. In Drupal 7, some of the functionality provided by image-related modules from the community has been moved into the core and simplified.
Note
Features from the Imagefield module, the Image API module and the Imagecache module have been moved into core.
