Abstract
An image display system is disclosed that enables users to navigate very large digital images quickly and seamlessly. The system is optimized to transmit image data from a disk drive at high data rates. The image data is stored on the disk drive in a file format optimized for high speed retrieval, display, and seamless navigation. The image display system can be cascaded for showing two or more contiguous images.

A method of storing an image on a storage device in a tiled format, comprising:
- formatting the storage device to include a block size that is an integer multiple of a tile size, wherein the tile size corresponds to a display output;
- reading pixel data of a source image;
- generating, from the read pixel data, a first tile and a second tile, wherein the first tile and the second tile each have overlapping portions that overlap by an adjustable amount, and the overlapping portions include substantially identical pixel data;
- storing the first tile and the second tile on the storage device;
- and
- repeating the reading, generating, and storing a plurality of times to store the image,
- wherein the image is stored on the storage device as a contiguous string of data.
