It truly is all about the money! Offering high resolution images in CD or DVD format will give you the benefit of printing images yourself for gifts or later while still getting your photographer to create your album and possibly large prints. By not having these rights, you are relying on purchasing all prints from your photographer, having all family purchase prints from your photographer, and have to go back to your photographer down the road if you ever want photographs later. If you do go with a package that does not include high res. images, make sure to ask your photographer how long your images will be available to have reprints made and if they are backed up for a certain number of years.
