A new version of the API (v4) is available here: developers.linode.com.

Image Methods

Linode Images lets you keep gold-master images without keeping an active Linode for deployments. You can deploy new Linodes from your gold-master image with ease. These calls allow you to manage the images that are associated with your account.

Use the linode.disk.imagize() and linode.disk.createfromimage() methods to create and deploy images.
