module: smartos_image_info
short_description: Get SmartOS image details.
description:
    - Retrieve information about all installed images on SmartOS.
    - This module was called C(smartos_image_facts) before Ansible 2.9, returning C(ansible_facts).
      Note that the M(smartos_image_info) module no longer returns C(ansible_facts)!

        description:
            - Criteria for selecting image. Can be any value from image
              manifest and 'published_date', 'published', 'source', 'clones',
              and 'size'. More information can be found at U(https://smartos.org/man/1m/imgadm)
