Question: I was unable to find resources to understand how Docker Hub images can be managed.

I have an image tagged with V0.0.1 and built a new one tagged V0.0.2. Now I want to remove the V0.0.1 image as the new version is built differently and I don't want users to pull the old image.

Answer: 
Its possible, click in details on repository after click in Settings. Look the image:

there is a big red "DELETE" button in "Settings" Tab when you login into your Docker Hub.
