The greatest impact of the advent of the digital age on art history scholars is the enormous change in the way of image materials acquired, applied, published and shared. A large number of slides used to study and teach art history have been digitized. Digital images are almost readily available on the web - just know how to find them. Such a digital environment should be conducive to the research and development of art history. However, art history scholars face the transformation of digital technology, and the speed of adaptation seems to be much slower than the other humanities. The reason is worth exploring. This paper tries to observe the daily life behavior of curators in the National Palace Museum by Participant Observation method, and analyzes the image needs of the daily work. Secondly, it focuses on the study of museum art history and discusses the image needs of curators from the art history research methodology. It also analyzes the needs of image management tools and the obstacles of the use of digital images as well as the role of museums in the development of digital art history. Finally, the influence of the production and utilization of images in the National Palace Museum on the digital art history is introduced.
