Measure the side of the picture frame. Mark the frame with a pencil one-third down from the top. Repeat the measurement and marking on the other side of the picture frame.
Set a framing D-ring over one pencil mark. Line the screw hole in the D-ring up with the pencil mark on the frame.
Screw the D-ring to the picture frame, using the small screw that came with the ring. Attach a second D-ring to the other side of the frame, using the same method.
Pass one end of a piece of picture wire through one D-ring. Fold the end of the wire over and twist it together to secure the wire.
Stretch the wire across to the second D-ring and pass the end through. Leave the wire slack enough to sag 1 to 2 inches after hanging. Twist this end together to secure. Hang the picture by the wire.
