Search the Internet or home decor magazines for pictures of photograph displays you like that will fit your home or space.
Choose the right spot in your house. Staircases and fireplace mantles are common areas for photograph groupings, but many walls can be used for this purpose. Consider the traffic through the part of the house with the photographs because you do not want to place them in high traffic areas where pictures may be broken.
Choose your frames. Frames may be grouped together in a variety of sizes. It is best to keep the frame color the same if grouping many photos. When a lot of frames are used together, they are typically hung in rows.
Check the back of your frames for hardware. Many come with the needed hardware, but some do not. If a frame lacks hardware, this can be bought at your local hardware store. Hanging hardware is typically sold by the weight of the frame it will hold. If you are using wooden frames, hardware may be carefully hammered into the frame, but you need to assess how to best attach hardware if you need to do it.
Test your chosen arrangement by laying the frames on the floor as you plan to hang them. This is one way you can move them around and see what looks the best before hammering nails into the wall.
Hang pictures, and enjoy the fruits of your labor!
