Claim Text:
1. A method of retrieving images over a network communication channel for display on a user computing device, the method comprising steps of: issuing a first request from the user computing device to one or more servers, over one or more network communication channels, the first request being for a first update data parcel corresponding to a first derivative image of a predetermined image, the predetermined image corresponding to source image data, the first update data parcel uniquely forming a first discrete portion of the predetermined image, wherein the first update data parcel is selected based on a first user-controlled image viewpoint on the user computing device relative to the predetermined image; receiving the first update data parcel at the user computing device from the one or more servers over the one or more network communication channels, the step of receiving the first update data parcel being performed after the step of issuing the first request; displaying the first discrete portion on the user computing device using the first update data parcel, the step of displaying the first discrete portion being performed after the step of receiving the first update data parcel; issuing a second request from the user computing device to the one or more servers, over the one or more network communication channels, the second request being for a second update data parcel corresponding to a second derivative image of the predetermined image, the second update data parcel uniquely forming a second discrete portion of the predetermined image, wherein the second update data parcel is selected based on a second user-controlled image viewpoint on the user computing device relative to the predetermined image, the second user-controlled image viewpoint being different from the first user-controlled image viewpoint; receiving the second update data parcel at the user computing device from the one or more servers over the one or more network communication channels, the step of receiving the second update data parcel being performed after the step of issuing the second request; displaying the second discrete portion on the user computing device using the second update data parcel, the step of displaying the second discrete portion being performed after the step of receiving the second update data parcel; wherein: a series of K1-N derivative images of progressively lower image resolution comprises the first derivative image and the second derivative image, the series of K1-N of derivative images resulting from processing the source image data, series image K0 being subdivided into a regular array wherein each resulting image parcel of the array has a predetermined pixel resolution and a predetermined color or bit per pixel depth, resolution of the series K1-N of derivative images being related to resolution of the source image data or predecessor image in the series by a factor of two, and the array subdivision being related by a factor of two.
