Warning. As I was working on my previous post, I notices an interesting incompatibility between the WordPress template I was using and Google Maps. The template in use has a CSS configuration of:

.entry_content img { max-width: 100% ; }

The previous css seems minor enough, but, this declaration affected the Google Map on the page. The result is a map that shows no zoom controls. Instead, where the controls should be, they display as small white marks. In the event that you happen upon a template that does not seem to be compatible with Google Maps (because the zoom controls are missing) check to see if there is a CSS declaration defining “img {max-width: 100% }” in a manner it might be affecting the map. If so, you will need to create a CSS declaration that will override this command. It appears that img max-width must be configured to “none,” or the controls will be incorrectly displayed.
