The problem with you code is that it hits glance api to create these images but
it should use nova api instead. I think the correct interface is server.create_image
so the code may look like

servers = openstack_connection.compute.servers(details=True, hostname='my_server'):
openstack_connection.compute.create_server_image(servers[0], image_name, metadata)

IIRC the image may inherit the properties of the source image you initially used to
launch these instances, so you may need to call openstack_connection.image.update_image
to add the properties you want to add.

# by the way "servers = servers[0]" and "images = images[0]" look quite confusing
# because you use plural for both and I may suggest "serer = servers[0]".
