An inquiring unit displays, before execution of a deletion process of deleting a to-be-deleted image IMP from an album page, a to-be-deleted image list for inquiring whether or not to execute a deletion process on the to-be-deleted image IMP on an album screen. A user selects an image display cell CE of a to-be-deleted image IMP to be kept in the album page and selects a keep button. Accordingly, the to-be-deleted image IMP whose image display cell CE has been selected is kept in the album page. This is user-friendly compared with a case were a to-be-deleted image IMP is deleted without any notice to the user.
