Short: use the save CLI command.

You can pull the image on a computer that have access to the internet.

sudo docker pull ubuntu

Then you can save this image to a file

sudo docker save -o ubuntu_image.docker ubuntu

Transfer the file on the offline computer (USB/CD/whatever) and load the image from the file:

sudo docker load -i ubuntu_image.docker

(On older versions this was just docker load image.docker, see comments for more info.)
