When navigation halts a high resolution image is loaded (according to viewer image size options). This image is loaded in the respective components and thrown away when navigating to a new node. When going back to the previous node the high resolution image needs to be loaded again.
If the high resolution image is loaded by the node and stored in the node cache (replacing the lower resolution image) it would not need to be loaded again when navigating back to the node and the high res image would be shown immediately when navigating back to a previously visited node.
