-- Lists all the image IDs for the specified repository.
--
-- You can filter images based on whether or not they are tagged by using
-- the @tagStatus@ filter and specifying either @TAGGED@, @UNTAGGED@ or
-- @ANY@. For example, you can filter your results to return only
-- @UNTAGGED@ images and then pipe that result to a BatchDeleteImage
-- operation to delete them. Or, you can filter your results to return only
-- @TAGGED@ images to list all of the tags in your repository.
--
-- This operation returns paginated results.
