google maps marker strangely stretched issue

I've seen various forms of stretched tiles and distorted controls, but this is the first time I see stretched markers and shadows. If we're lucky, adding these lines to your CSS or styles will unstretch the map and markers.

 #map_geolocation label { width: auto; display:inline; }
 #map_geolocation img { max-height: none; max-width: none; }

I tried your attached code and it looks OK the way it is.

Are you using twitter bootstrap? If so, try to add the following stylesheet.

div#map_geolocation img {
  max-width:none;
}
