Bishops’ conferences determine if images of Christ and the saints may be covered:
26. The practice of covering the crosses and images in the church may be observed, if the episcopal conference should so decide. The crosses are to be covered until the end of the celebration of the Lord’s passion on Good Friday. Images are to remain covered until the beginning of the Easter Vigil. (Roman Missal, rubric Saturday of the fourth week of Lent.)
