If you mean access to the tile image dom node, I don't know any straightforward solution but a tileset script of your own.
You can form your tile url by quadkey or geohash formulas. That is like an id but still you have to iterate through the tiles and compare src property to find a certain tile image. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
