Put on a pair of heavy work gloves. This is especially important if the window glass broke into shards, you don't want your hands exposed to the sharp pieces.

Tear off a piece of duct tape several inches long. Use the sticky side of the duct tape to pick up any small pieces of window glass sitting inside the window frame. Place the tape against the glass pieces, and push down slightly until the glass sticks to the tape. Lift the tape and glass up and away from the frame. Do not attempt to pickup any glass with your fingers, even small pieces of glass can be razor sharp.

Remove and long glass shards from the window frame. If the crack or hole is large enough, it may leave many jagged pieces attached to the window frame. Apply a generous coat of linseed oil to the putty holding the glass to the frame. The oil will soften the putty and make it easy to remove. Let the oil soak into the putty for several hours. Use a putty knife the remove the putty holding the glass in place. You should now be able to pull the glass free from the frame.

Measure the area of the window frame from which you removed the glass. Cut a piece of heavy duty plastic sheeting to that size. Place the sheeting over the area, and staple it to the window frame. Use several staples along all four sides so that rain will not seep inside the house. The plastic sheeting will work well until you can replace the glass.
