When image data sets are inserted in image data insertion areas in a
template, the image data sets can be set preferably in the insertion
areas with easy operation. A user connects a user terminal to a print
order reception center via a network, and uploads the image data sets to
be used. The user specifies reference points in the respective image data
sets by using instruction input means. An order reception server displays
composite images generated by matching the image data reference points
with reference points predetermined in each of template data candidates
at the time the template candidates are displayed.
