PROBLEM TO BE SOLVED: To provide a data processor, etc., to enable a user to easily perform data processing on a WWW server, etc. SOLUTION: An original image file before correction processing is saved by duplicating and storing it in a prescribed area of a storage device before applying the correction processing to an image file. The original image file is replaced with a processed image file obtained by applying the correction processing to the original image file. If necessary, the image file before the correction processing is restored by replacing the processed image file with the saved original file. In addition, the processed image file and the original image file stored in the storage device are managed by associating them with each other by describing the file name of the original image file in the header of the processed image file.
