I follow our hospice clients for a year of bereavement services, and recently went to visit a husband whose wife had died. He was eager to show me pictures he'd taken of lying in the casket and kept saying, "She looks so beautiful," and "She looks so peaceful." You could tell those pictures meant the world to him and were already easing his grieving process a little.
I imagine it helped soothe any pangs of guilt. Many people use the pictures for that very reason, to remind themselves of how everything worked out for the best and all is as it should be.
