When a user who once ordered generation of a photo album of an event such as a wedding orders generation of another photo album of the same event by using a different template, image editing can be carried out efficiently. In each order, the template ID used in the order and image specification information identifying selected images are recorded. Correspondence between image insertion areas in templates is recorded as correspondence information. When the order using the differential template is placed, the image specification information and the correspondence information is referred to, and an image editing screen is displayed by inserting the selected images used in the previous order in the image insertion areas in the template used in the present order.

A system and method for improving installation of a prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation.

A system and method for improving installation of a prosthesis, particularly an acetabular cup. The system and method may include implementation of a constant velocity relative motion between a prosthesis and an installation site. For example, an installation system may be fixed relative to the installation site, with the prosthesis fixed into an initial position. The prosthesis is moved at constant speed (i.e., with minimal if any acceleration or applied impulses) relative to the installation site. That is, one or both of the prosthesis or the installation site may be in motion. Resistive forces to installation of a prosthesis may thus be reduced by maintaining the prosthesis constantly in motion relative to the installation site. Securing a processing/implanting tool directly to the installation site may offer advantages.
