SnapDMG is simple enough to explain in four moments: prepare the canvas, preview the artwork, build the DMG, and open the finished disk image.
02 / Preview
Preview the disk.
Attach a JPG or PNG and check the DMG window before export. 1080 x 700 is the recommended canvas when you want the artwork to stay crisp.
