* `SHARED SIZE` is the amount of space that an image shares with another one (i.e. their common data)
* `UNIQUE SIZE` is the amount of space that is only used by a given image
* `SIZE` is the virtual size of the image, it is the sum of `SHARED SIZE` and `UNIQUE SIZE`

> Network information is not shown because it does not consume disk space.
