Is that I have a large map, the screen can only display a part, but I can drag the image to show the other part, not shown is similar to the map,
Or a change of demand, is there any plug-in can implement a custom map, map is not derived from GPS real figure, but I own a large map images,
Have to settle for second best, so that the map plugin can display only satellite image or topographic map without any text (streets, place names), writing my own mark up,
