1. A method for communicating a digital image over a network, comprising the steps of:
- storing a digital image having a plurality of image tiles at a plurality of resolutions on a server computer;
in response to a user request for a given image portion at a given resolution, identifying those image tiles which are necessary to display the given image portion at the given resolution; and
determining whether the image tiles which are necessary to display the given image portion at the given resolution are present in a user tile database, and if not, automatically downloading from the server computer those image tiles which are necessary to display the given image portion at the given resolution but are not present in the user tile database.

19. A method for communicating a digital image over a network, comprising the steps of:
-
storing a digital image having a plurality of image tiles at a plurality of resolutions on a server computer; in response to a user request for a given image portion at a given resolution, identifying by the server computer those image tiles which are necessary to display the given image portion at the given resolution; and transmitting from the server computer those image tiles which are necessary to display the given image portion at the given resolution, thereby obviating the need to transmit an offset table. - View Dependent Claims (20, 21, 22, 23, 24)
