Methods of caching tile image constituents of image-mosaics enable a substantially smooth real-time display of portions of the image-mosaic in a view during panning, resizing, or zooming of the view. The method includes using a predictive algorithm to identify tile images to be retrieved from a remote store through a local area network, and for sequencing requests for the retrieval of tile images from the remote store. A scheduler calculates time spent in retrieving and servicing each tile image retrieval request and proportionately pauses retrieval of tile images after each request is serviced in order to prevent over utilizing LAN resources. The advantages are that tile images to be displayed are cached in accordance with a priority to facilitate image display while network data transfers are distributed in time.
