Default behavious is to show the information bubble when embedding a Google Map in your web page. Some times this is not a desired behaviour, and you only want to show the placemark. After a little digging this Google Groups thread provided a very simple solution to the problem.

Add the iwloc-parameter with value near. Here’s an example:
View Larger Map
View Larger Map

So the string to insert is

&iwloc=near

somewhere in between. Take a look at my source code if you’re unsure.
