# Images

Images are what is used to build containers. Each image defines the pieces required to build and configure a container and can be reused many times. The **Images** section in Portainer lets you interact with the images in an environment.

You can pull images from Docker Hub or any other [registry](/admin/registries/add.md):

{% content-ref url="/pages/-MhuWfJo1EepuXnb5TXs" %}
[Pull an image](/user/docker/images/pull.md)
{% endcontent-ref %}

You can also view a list of the images that are currently available in an environment, including their IDs, usage states, tags, sizes and creation dates. There are many other options available:

{% content-ref url="/pages/-MhuZcAkEsEnGJ-4S150" %}
[Build a new image](/user/docker/images/build.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MhuZOq1zyCwH8V0e1d4" %}
[Import an image](/user/docker/images/import.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MhuZXvqVu9MvagSdAdD" %}
