You can easily make a static map using GMaps.js:
url = GMaps.staticMapURL({
size: [610, 350],
lat: -12.043333,
lng: -77.028333
});
$('<img/>').attr('src', url)
.appendTo('#map');
You must define a size and the latitude and longitude of the map's center.
Note: You also can define zoom (by default is 15, unless zoom is set to false, in which case Google will set zoom based on marker positions).
