A print instruction apparatus is connected to a storage medium where an image file having image data contained therein is stored, and instructs a printing device to print an image selected by a user using a given communication standard. In the print instruction apparatus, when a set file in which directly accessible top image data and subsequent image data are contained is stored in the storage medium, wherein the subsequent image data is accessible at an address determined with an offset from a given position of the top image data as the origin, the offset being registered in a header of the top image data, an image ID configured to individually identify each piece of image data contained in the set file is set by analyzing the set file, and a list in which the set image ID and positional information based on the registered offset for reading the corresponding image data are contained so as to be associated with each other is created
