Abstract: A recording medium in which a purchased image protected by a copyright or the like has been stored and a recording medium in which a user image has been stored is set, the purchased image as encrypted is decrypted and the images stored in both mediums are processed. The ID of a created image, user image data, link information representing encrypted purchased image data or the storage location of the purchased image data, and data specifying an image processing mode and the number of prints, are stored in a recording medium. In a DPE shop or the like, the purchased image data stored in the recording medium is decrypted, and the image processed by the user is reconstructed and printed in accordance with the data stored in the recording medium. A management center may give the allowance of use of the purchased image to the DPE shop, and the management center draws royalties from the accounts of individual DPE shops, sums the royalties and pays them into the accounts of individual proprietors of rights.
