A nontransitory storage medium storing an information processing program to be executed by an information processing device, the program being designed to have the device function as: a display controlling section for controlling a display portion to display icon images; a transmission controlling section for controlling a transmitting portion to transmit user-selected targeted data among data corresponding to the icon images; an obtainment controlling section for controlling an obtaining portion to obtain converted data created by an external device based on the targeted data; and a storage controlling section for storing reduced-size image data created using the targeted data, into a storage portion such that the reduced-size image data is associated with the targeted data. For each data with which the reduced-size image data is associated, the display portion displays a reduced-size image corresponding to the reduced-size image data as an icon image.
