An image processor is connectable with a storing medium storing still image data corresponding to a still image and moving image data corresponding to a moving image, the moving image data including a plurality of sets of frame image data corresponding to a plurality of frame images respectively. The image processor includes an outputting unit, an extracting unit, and index image producing unit, and a layout unit. The outputting unit outputs an image list having a first layout area having a first layout size and a second layout area having a second layout size. The extracting unit extracts at least two sets of frame image data from the plurality of sets of frame image data. The index image producing unit produces a first index image from the still image data and a plurality of second index images from the extracted frame image data. The layout unit lays out the first index image in the first layout area and the plurality of second index images in the second layout area.
