To always generate photo albums with consistent quality in the case of generating the photo albums on events such as weddings.

A professional photographer photographs the bride and groom at a wedding. Images are read from a developed film and stored in a file server. A photo album editing operation such as selection of the images to be included in the album is carried out with reference to an editing screen 30 including a catalog display field 31 having image data sets representing the images and a template display field 33 displaying a template. Sample images having composition of images to be inserted in image insertion areas in the template in the template display field 33 are inserted as guide images in the image insertion areas. An operator thereby easily selects the images to be inserted in the image insertion areas by referring to the guide images.
