The verb “hang” means “to suspend” and it has two forms of the past tense: “hanged” and “hung.” The use of these words depends on their meaning. “Hanged” is used to mean “suspended with the intention of killing” and refers to a person; “hung” is used for objects or for people who are suspended for reasons other than to be killed.

“Picture” is an object that was suspended by a nail on the wall.
