If you want to put a map on your web site using Google Maps, the easiest way to do that is by going to WikiMapia, finding the place you want, then going to the menu and selected "Map on your page". You'll be presented with a box that lets you pick the size and exact starting location of your map, and you'll be given a very simple HTML snippet (an iframe) you can put anywhere.

For example, I found my home in Berlin and was given the following snippet:

<iframe src=http://wikimapia.org/s/#y=52506879&x=13318394&z=19&l=0&m=a width=400 height=208 frameborder=0></iframe>

I had to change the HTML to XHTML myself by adding quotes around the attribute values and escaping the ampersands in the URL:

<iframe src="http://wikimapia.org/s/#y=52506879&amp;x=13318394&amp;z=19&amp;l=0&amp;m=a" width="400" height="208" frameborder="0"></iframe>

Unfortunately, iframe is deprecated in XHTML Strict, so this would make my page invalid. The way to embed a frame on a page in XHTML Strict is to use an object tag instead like so:

<object type="text/html" data="http://wikimapia.org/s/#y=52506879&amp;x=13318394&amp;z=19&amp;l=0&amp;m=a" width="400" height="208" style="border:0"></object>

It seems WikiMapia doesn't support the object tag when used with Internet Explorer. Well, as long as you're not using IE, you can see where I live in Berlin! The rest of you can click here instead.
