Get image name within container

I'm trying to get the name of the container image from within the container.
I tried to look around the Downward APIs, but it seems that it's not possile:
https://kubernetes.io/docs/tasks/inject-data-application/downward-api-volume-expose-pod-information/

For now my workaround is:

      env:
        - name: IMAGE
          value: "myimage:latest"

But do you have a better way?

Cheers
