title: How to share google compute engine images across projects?
body: <p><a href="https://developers.google.com/compute/docs/overview">From documentation</a> I know that images are global resources that <em>"are accessible by any resource in any zone within the same project"</em>.</p>
  
  <p>I am looking for a functionality similar to sharing AMIs within AWS. That is, I create an image, make it public and anyone can use it immediately.</p>
  
  <p>How to best achieve something similar in GCE? The problem is that the image I need to create would be large - around 100GB. So I am looking for a way of sharing the image that wouldn't involve slow copying (e.g. from a bucket in google cloud storage).</p>
