using a Go template.
Valid placeholders for the Go template are listed below:

| `.ID` | Image ID |
| `.CreatedSince` | Elapsed time since the image was created if --human=true, otherwise timestamp of when image was created |

| `.CreatedAt` | Timestamp of when image was created |
| `.CreatedBy` | Command that was used to create the image |

| `.CreatedBy` | Command that was used to create the image |
| `.Size` | Image disk size |
| `.Comment` | Comment for image |
When using the `--format` option, the `history` command will either
output the data exactly as the template declares or, when using the
`table` directive, will include column headers as well.
The following example uses a template without headers and outputs the
`ID` and `CreatedSince` entries separated by a colon for all images:
```bash
$ docker images --format "{{.ID}}: {{.Created}} ago"
