Attach photos to wooden skewers, cut to varying heights, and secure them inside a vase or other decorative holder. Use any accents you would like to make it seem more festive. I would strongly recommend using black and white or sepia colored photographs. If you have photos on a disk or flash drive, you can get them printed at stores, such as Walmart, for as little as 20 cents per photo.
Cheap frames, spraypaint, and ducktape (I think I would use white to match the frames). Print photos on vellum, and staple or tape them into the frame. Place a candle in the middle for a personalized, glowing centerpiece. Cute!
