Here are some steps you can follow to hang a heavy picture:

1. Locate the hanging point on the wall and lightly mark it with a pencil.
2. Measure the distance from the hanging point to the sides of the frame and lightly mark each side on the wall.
3. Measure the top of the frame to the hanging point and lightly mark on the wall.
4. Drill a hole into the wall at each marked point.
5. Insert wall anchors into each hole.
6. Screw in hooks or screws into each anchor.
7. Hang your picture on the hooks or screws.

If you're hanging your picture on drywall with no stud, you can use drywall anchors (also called screw-in anchors) instead of drilling holes into the wall.

Another solution for hanging heavy pictures is to use a rail-cable hanging kit. This kit includes a rail that is mounted on the wall and cables that hang down from it. You can then attach your picture to the cables using hooks.
