                             cert=None,
                             key=None,

                             aliases=None,
                             public=False,
                             auto_update=False,
                             _raw=False):
    ''' Create an image from simplestreams

        server :
            Simplestreams server URI

        alias :
            The alias of the image to retrieve

        remote_addr :
            An URL to a remote Server, you also have to give cert and key if
            you provide remote_addr and its a TCP Address!

            Examples:
                https://myserver.lan:8443
                /var/lib/mysocket.sock

        cert :
            PEM Formatted SSL Certificate.

            Examples:
                ~/.config/lxc/client.crt

        key :
            PEM Formatted SSL Key.

            Examples:
                ~/.config/lxc/client.key

        verify_cert : True
            Wherever to verify the cert, this is by default True
            but in the most cases you want to set it off as LXD
            normaly uses self-signed certificates.

        aliases : []
            List of aliases to append to the copied image

        public : False
            Make this image public available

        auto_update : False
            Should LXD auto update that image?

        _raw : False
            Return the raw pylxd object or a dict of the image?

        CLI Examples:

        ..code-block:: bash

            $ salt '*' lxd.image_from_simplestreams "https://cloud-images.ubuntu.com/releases" "trusty/amd64" aliases='["t", "trusty/amd64"]' auto_update=True
    '''
    if aliases is None:
        aliases = []

    client = pylxd_client_get(remote_addr, cert, key, verify_cert)

    try:
        image = client.images.create_from_simplestreams(
            server, alias, public=public, auto_update=auto_update
        )
    except pylxd.exceptions.LXDAPIException as e:
        raise CommandExecutionError(six.text_type(e))

    # Aliases support
    for alias in aliases:
        image_alias_add(image, alias)

    if _raw:
        return image

    return _pylxd_model_to_dict(image)
