For the basic instructions, please see the Making Images With Background
Pictures section. If your final disk image does not have the icons in the
right positions:
- Make sure that your configuration has a layout selected.
- Check that your layout includes all of the files whose icons you want
to place.
- When creating the disk image, make sure that the source folder you are
dropping onto DropDMG includes all of the files in your layout.
- The files in the source folder must have the same names as those in the
layout. If DropDMG encounters a file that is not in the layout, it will
leave that file’s icon in the default position.
