DMG Canvas

If you need to create a disc image, DMG Canvas is an application for Mac that will give it that personal flavour that will distinguish the windows that will appear after mounting a file of this kind.

Use a graphic editor to create the background for the window. Adjust the size or set the position of the picture and dimensions manually. If you don't want a picture as background you can choose a colour. You can also modify the size of the icons in the window.

They are only a small sample of the modifications you can perform. You will be able to change name and icon of the volume, format, code, compression and more. Don't forget to include legal info about the disc image.
