-In general, you can use the repository name to remove an image but the Image ID is sometimes needed. The most common situation where you are likely to need the Image ID is after an image has been updated on DockerHub and pulled down to your Raspberry Pi. You will find two containers with the same name. One will be tagged "latest" (the running version) while the other will be tagged "<none>" (the prior version). You use the Image ID to resolve the ambiguity.
