Abstract: When the user selects one or more thumbnail images G and one uploading destination from an image list screen GW, an image selection tray PT showing the thumbnail images G and an uploading screen AW corresponding to a web browser are displayed. When the user selects the thumbnail images G from the image selection tray PT, the image paths GP corresponding to the selected thumbnail images G are acquired. In this manner, the image files can be uploaded only by requiring the user to paste the acquired image paths in image path input sections GR on the uploading screen AW. Accordingly, the user can upload image files to an optional uploading destination by simple operation.
