WordPress & Google Maps

Hi,

I have troubles including Google Maps in my Posts. When I simply CopyPaste the iFrame-code in the html-source of a posts an hit update page right after that the map will be displayed, everything works like a charm. But as soon as I switch to the visual (WYSIGYG) version of the editor, the iFrame code just dissappears. I found a tutorial on wordpress.com how to put Google Maps in a post, but that just does not work.

So here are my assumptions/questions: Does wordpress’ editor delete all iframe-sourcecode by default (and this is not an error)? And does wordpress.com use a plugin for their way of googlemaps integration?

If so – how can I use Google Maps in my post, or what plugin does wordpress.com use / would you recommend me?

Thanks in advance,
Luke
