Resource Requirement

Hello！

I’m a openstack beginner in China and I need your help.

I am following the doc. on https://docs.openstack.org/sahara/pike/user/vanilla-plugin.html, but the image(http://sahara-files.mirantis.com/images/upstream) is 404. Could you please provide me with a new dowload link? It will be really helpful.

I'm sorry if there is any bother.
