My wife is often very picky about the grocery store. Being able to attach a picture to an item would allow me to pick up EXACTLY what she wants. Saving me the asspain of having to go back to the store to pick up the items I missed, or just plain got wrong. This results in more free time for me and less time getting yelled at because she TOLD me exactly what it was I was supposed to get. Although often what she says and what she wants and what she pictures in her mind are often four or five different things then what I interpret them to be. Without a picture it is a losing battle.
