wp_googlemap_shortcode.php

//Google Maps Shortcode
function fn_googleMaps($atts, $content = null) {
 extract (shortcode_atts (array (
  "width" => '640',
  "height" => '480',
  "src" => ''
 ), $atts));
 return '<iframe width="'.$width.'" height="'.$height.'" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="'.$src.'"></iframe>';
}
