When we work with images we relieve ourselves of the pressure of words. Far too often words are literal and absolute, and images allow the pressure to come off that channel, with all that it implies and to relax into an image. An image allows all the content to find an expression and hold it, like a vessel.
Images can come from a patient recounting their dreams, or from closing their eyes and checking what comes up when they are trying to describe sensations, feelings, and so forth. Homeopathy gets landlocked in language without appropriate mining in etymology. Have a dig around the origins of words can be so helpful. We also need to be culturally aware that words can hold different meanings in various languages, and with consultations reaching all over the world, we need to be able to do some research into the realms of meaning here.
It is often helpful to consider to mythology or original fairy stories to find images associated with those from both dreams or short imaginings in the consulting room. Children of course have no problem expressing their imagination and the drawings often brought as gifts or done in the consulting room are a treasure house of images which provide such a direct route to the assistance that they require at that time.
