Hi.

When you take a map image, and create tiles by a program, you get not only tiles folder (with images) but also a html-file to show your map. Open it and find this function.

Check zhuk.cc/wiki/index.php/Zh_GoogleMap_CustomMapType

You can see

Code:

  var gallPetersMapType = new google.maps.ImageMapType({
    getTileUrl: function(coord, zoom) {
      var numTiles = 1 << zoom;

      // Don't wrap tiles vertically.
      if (coord.y < 0 || coord.y >= numTiles) {
        return null;
      }

      // Wrap tiles horizontally.
      var x = ((coord.x % numTiles) + numTiles) % numTiles;

      // For simplicity, we use a tileset consisting of 1 tile at zoom level 0
      // and 4 tiles at zoom level 1.
      var baseURL = 'images/';
      baseURL += 'gall-peters_' + zoom + '_' + x + '_' + coord.y + '.png';
      return baseURL;
    },
    tileSize: new google.maps.Size(800, 512),
    minZoom: 0,
    maxZoom: 1,
    name: 'Gall-Peters'
  });

In this case the function in that place

Code:

getTileUrl: function(coord, zoom) {

begin of function

Code:

function(coord, zoom) {

and the end of function is

Code:

	return baseURL;
    }

And in your file find getTileUrl: - after that - your's function
