A couple of different things are happening here. One is that in many cases the image exists but is inaccessible to the project using it. I'm fixing those one by one.

The other issue is that gclient.images.list() returns owned images but doesn't return private images that are visible to the current project but not public or owned by that project. I don't know why, but the upcoming code addresses this, badly.
