This one is the interesting part, I think:
http://code.google.com/apis/maps/doc....html#MapTypes
Add/modify this code in the map.php und you'll be fine.
For example (without testing)
replace
Code:
var map = new GMap2(document.getElementById("map"));
with
Code:
var map = new GMap2(document.getElementById("map"));
map.setMapType(G_SATELLITE_MAP);
and a satellite view should be displayed.
The API is huge, take some time to explorere, it's fun I think
