There are two ways you can do the map thing. One way is to create a new page with the detailed map on it, and link to that page in the usual way. This is best if you want to put some text with navigation instructions alongside the map.
The other way is as I have done click here by linking directly to a graphic. Of course you will need to ensure that the graphic is uploaded too. In Page Plus I linked to a file on my hard disk, and it was uploaded automatically when I published the website.
Here I have linked to the whole map. You can also link to a hotspot on the map, which is handy if you want the user to be able to zoom in to Florida Pines, or to Orlando Airport.
