NetBoot images are really folders containing all the items necessary to facilitate booting over the network. These NetBoot image folders are easy to spot, because the name of the folder always ends with .nbi.
In order for a NetBoot server to use a NetBoot image, the image must reside in the NetBoot share points. The Server Admin utility automatically creates the NetBoot share points on every server volume in the Library/NetBoot/NetBootSP# folder. For each different server volume, the # is incremented by one, with the first column number being zero.
You can use the Network Image Utility as a centralized utility to manage your NetBoot images. The Network Image Utility maintains a list of all your NetBoot images for easy reference. If an image isn't in the Network Image Utility image list, you have to add it manually. More important, the Network Image Utility can be used to edit existing NetBoot images as your requirements change.
