The image display control device includes a thumbnail image display control unit that displays a thumbnail image of a tomographic image forming a three-dimensional image, a display instruction receiving unit that receives an instruction to display the three-dimensional image, and a tomographic image display control unit that displays a plurality of tomographic images on a display screen which is different from a display screen on which the thumbnail image is displayed such that the tomographic images are sequentially switchable when the instruction to display the three-dimensional image is received. The thumbnail image display control unit newly generates a thumbnail image of the tomographic image displayed immediately before the display of the tomographic image ends, changes the current thumbnail image to the new thumbnail image, and displays the new thumbnail image.
