Google Maps' icon not rendered in Liferay 6.2

When using Google Maps in Liferay  6.2.
All the icon in Google Maps are not rendered,

This is due to css conflict in Liferay 6.2 and Google Maps.

To resolve this problem, just need to add the following css.

.aui .gm-style img {
  max-width: none;
}

Done!!
