module: hcloud_image_info

short_description: Gather infos about your Hetzner Cloud images.


description:
    - Gather infos about your Hetzner Cloud images.
    - This module was called C(hcloud_location_facts) before Ansible 2.9, returning C(ansible_facts) and C(hcloud_location_facts).
      Note that the M(hetzner.hcloud.hcloud_image_info) module no longer returns C(ansible_facts) and the value was renamed to C(hcloud_image_info)!
