I never use the word "image" when referring to a photograph. It implies that all the photograph is is an image of what is pictured. An image is not a photograph. Photographs are pictures. Images are not. I am a photographer, or sometimes, a picture-maker. I am not, never was, and never will be an image-maker.
Also, images are what appear on the ground glass. They are not yet photographs.
Those who use the word "image" when they really mean "photograph" are usually indulging (consciously or more often, unconsciously) in pretentious and high-sounding languange.
