Go to Joomla administrator / Components / JEmbedAll / Configure Google Maps for setting how the maps will be shown on your Joomla site: 'Configure map' (and the red pin item in Joomla 2.5) is for the [ googlemap ] and 'Configure directions' (and blue pin item in Joomla 2.5) is for [ googledirections ], the API used for asking Directions with Google maps.
To embed a map in a Joomla site article or module use the following codes without spaces: [ googlemap = address ] or [ googlemap = latitude,longitude ] where the latitude,longitude are the coordinates in decimal degrees.
Example 1
Replace the "address" string with the address which location you want to show on the map: or [ googlemap = London, Great Britain, UK ] or [ googlemap = Tokyo,Japan ]
Example 2
Replace the "latitude" and "longitude" strings with the coordinates which location you want to show on the map. The coordinates must be expressed as decimal degrees: [ googlemap = 47.0745948,21.9374442 ] or [ googlemap = 51.5286416,-0.1015987 ]
You can override the current configuration for each map you are embedding like this:
[ googlemap = 47.0745948,21.9374442|ver=new|z=20|t=h|hl=ro] or [googlemap = Tokyo,Japan|version=embed|zoom=20|maptype=k|language=ja]
[ googlemap = 47.0745948,21.9374442|ver=new|z=20|t=h|hl=ro]
In the administrator section you can edit this string - you can change its name and the CSS code attached. Using the CSS code you can set the position on page and other attributes (like the margins).
