PLEASE be sure to donate if you use this extension! This extension needs to be considered as Editor's Choice for maps. I can't say enough nice things about GMapFP and I have been working with this extension for months!
The module turned out to be very clean and appealing with the ability to input your own hex# for base color and rollover colors for each state plus use a background behind your map without knowing CSS. You can also customize tooltips and links per state all in an easy to use backend module.
The only complaint was that you can only include one link per state and I was hoping to be able to add multiple links based on the text in the tooltip but I solved this by putting the links in the landing page of the state click (adding an extra click for the end user but functional).
Today I stumbled on a problem. The state links don't work in Firefox. I am not sure if they every worked as I made the rookie mistake of only testing in IE and Chrome.
All-in-all, it is a very clean, professional module that is easy to install and use even for a novice but I couldn't give it a top rating as the there was no demo or upfront documentation/support.
