An apparatus includes an association unit, a setting unit, and an arrangement unit. The association unit associates an image with a display region reference point through an image reference point of the image. Here, a number of display region reference points disposed in a display region is equal to or more than the number of images to be arranged in the display region. The setting unit sets, in the display region and for each image, an image reference point arrangement region based on a size of the image associated with the display region reference point and based on a position of the display region reference point associated with the image. The arrangement unit arranges each image in the display region by positioning the image reference point of the image within the image reference point arrangement region associated with the image.
