Is it permissible to hang pictures of deceased parents in the home, and if it is not permissible to hang them, is it permissible to keep them without hanging them?

If the parents' pictures are three-dimensional or drawn, it is not permissible to acquire or hang them, and they must be destroyed. However, if they are taken with a camera, it is preferable not to hang or acquire them, and it is forbidden to hang them if doing so leads to their veneration.
