Which of the following statements is true about managing Docker images?

The statement that images can be used to launch containers is correct because, in Docker, images serve as the blueprint for creating containers. When you run a Docker container, you are essentially instantiating an image. This process allows you to create an isolated environment that includes the application and all of its dependencies, facilitating easy deployment and scalability. Each container created from an image operates independently while sharing the underlying image, which promotes efficient resource utilization.

In contrast, other statements about Docker images are not accurate. For example, images can be removed once created if they are not being used by any existing containers. Additionally, images do not need to be stored locally as they can be pulled from Docker registries, which serve as centralized repositories. Lastly, although images can often be created using command-line interface tools, they can also be made using graphical user interfaces and other automation tools, emphasizing that command-line usage is not the sole method for image creation.
