To insert a map in your page, use the Map Creator and then copy the HTML text it generates into the page you are creating.
For example, the text:
(left bracket) gmap |id=map |center=-117.41226196289062, 33.00060174664655 |zoom=8 |width=300 |height=200 |align=None |control=Small |type=Map |points=-117.257080078125,33.04550781490999 (right bracket)
Generates the map:
[gmap |id=map |center=-117.41226196289062, 33.00060174664655 |zoom=8 |width=300 |height=200 |align=None |control=Small |type=Map |points=-117.257080078125,33.04550781490999]
and this is a satellite image of Kenya, I think near Mombasa:
[gmap |id=map |center=40.15331268310547, -2.9101249120129014 |zoom=4 |width=600 |height=400 |align=None |control=Small |type=Satellite |points=39.287109375,-2.8991526985043006]
