An image-displaying device includes a storing unit and a displaying unit. The storing unit stores correlation data between a plurality of thumbnails and a sequence of the plurality of thumbnails. The displaying unit is capable of displaying a predetermined maximum number of thumbnails based on the correlation data. If a displayed thumbnail is selected by a user, the displaying unit displays identification data identifying the selected thumbnail together with the selected thumbnail. If identification data is selected by a user, the displaying unit displays a thumbnail corresponding to the selected identification data.
