<human>:  What is the best way to hang a painting safely?
<bot>: The best way to hang a painting safely is to use a wall hanger that is rated to hold the weight of the painting, secure the hanger to wall studs with screws or nails, and use picture wire or hooks that are rated for the same weight or more than the painting. Make sure the picture wire or hooks are securely fastened to the hanger and the wall, and ensure that the wall material is appropriate to secure the hanger in place.
