Abstract

A method and system for archiving digital data on a server computer, and enabling a user, by means of a client computer, to interactively view a digital image derived from the digital data, the method including receiving an original HTML page by the client computer from the server computer, the original HTML page containing a view window within which a first image is displayed, the view window being partitioned into a plurality of sub-regions at least one of which contains a multiplicity of pixels, selecting a location within the view window corresponding to one of the plurality of sub-regions by the user, initial sending by the client computer to the server computer an indication of the sub-region selected by the user, creating by the server computer a new HTML page containing a link to an embedded image which corresponds to the indication, and further sending the new HTML page by the server computer to the client computer.
