I may have a borderline obsession with photos. They occupy I'd say 60% of my living room walls and they find themselves in all the other rooms of the house.
Here's just a sampling...
Living Room
Dining Room (yes, there's an empty spot!)
More Dining Room
Stairway (my hubby's one wall)
Bathroom
Oh geez, I just realized I have no photos in my kitchen! We'll have to see about changing that...
