How does Isabel Allende use imagery in Eva Luna?

Example of Imagery:

"In their hearts they knew that from that moment they would try to forget, to tear that horror from their souls, resolved never to speak of it, with the hope that time would erase it. Finally, slowly, exhausted, feet dragging, they returned home. Last came Rolf Carle, walking between two rows of skeletons, all equal in the desolation of death."
