I believe that personal items are part of what makes a house a home. There are a few rules that we like to follow, but there is nothing in these rules that would keep you from being able to smile at your favorite photos everyday.
If you follow these three rules for photos, you should be just fine:
1) Remove everything from the outside of your refrigerator and freezer. This includes photos, calendars, and even artwork. You have probably heard that kitchens and bathrooms sell homes.
