Araelium Group has released DMG Canvas, software for building customized disk images. Users drag and drop items to its window, and can lay out files in a customized order. The software additionally allows for customizing the icons, sizes and backgrounds, and remembers the location of contents in an image, allowing one-click rebuilds with updated source material.

Other features include displaying license agreements when an image is mounted, and a command line tool for producing automated workflows. DMG Canvas is freeware and supports both PowerPC and Intel Macs, but requires Mac OS X 10.5 or better.
