Framed wall collage? I want to create a wall of all black and white ...

I want to create a wall of all black and white framed photos of my kinfolk, I have 4x6 and 5x7 black frames adjectives different styles. How do I arrange the photos? I'm guessing it will hold 40 pictures or do you think this will look adhesive?
Exposed floorboards?
Answers:    Why don't you make it interesting and use some frames of different sizes that hold multiple photos something resembling this?
