An image processing system comprises a photocopier and an information processor. The photocopier scans and images each page of a document, creates a thumbnail image from each scanned image, and sends the thumbnail images to the information processor. Using the information processor, a user then specifies an image output sequence by rearranging the thumbnail images with a pointing device. The photocopier receives this output sequence information from the information processor, and using the printer section of the photocopier prints the scanned images according to the specified output sequence contained in the received sequence information.
