Go with pictures in frames for an elegant way to display photos at a party.
Consider the style of party where the photos will be displayed and choose your frames. Silver frames are great for an elegant party and wood frames would suit a more casual event.
Check out wedding favor and tabletop decor websites to find many miniature photo frames at bulk prices. The little frames are often used for place cards or table numbers.
Look in thrift stores for affordable frames. They don't have to match! You can simply spray-paint them all in your desired color.
Make copies of the pictures and size them to fit the frames.
Arrange framed photos in the center of guests' dining tables at a party as the centerpiece or around a floral arrangement.
Photos on the dining tables are a great way to get people mingling at the party as they will "table hop" to see each display.
You could even group the photos on each table by year for a graduation party or decade for anniversary parties.
