DeployStudio has a very nice background image that it uses by default for the NetBoot set. But you can customize the image that’s used if you wish to have something more, well, customized. Simply mount the DeployStudioRuntime sparseimage file from the DeployStudioRuntime nbi file that was created when you elected to generate the NetBoot set. You can do so by simply opening the nib file and then double-clicking on the sparse image. From here, browse into the System and then the Library and then the CoreServices directory in the NetBoot set. From here find the DefaultDesktop.jpg file. Replacing that file will replace the background that is used when you boot to the NetBoot set. The higher resolution the better!
