An image filing apparatus capable of inserting images into a sequence of stored images includes an input unit for entering images. A storage unit is provided for storing in a storage medium a file image comprising a plurality of pages of images entered from the input unit. Management circuitry manages a page sequence of individual images of the file image stored in the storage medium so that the file image can be reproduced in a predetermined page sequence. Adding circuitry adds an image newly entered from the input unit to the file image already stored in the storage medium. The management circuitry then manages the page sequence so that the file image, which includes the newly entered image added by the adding circuitry, can be changed in a reproduction sequence.
