Hot Maps has been created to allow webmasters to include any map from Google Maps inside Joomla website. With one purchase, you will get both Hot Maps plugin and module!
Once you install the module and publish it in appropriate module positions, you should enter location that should be displayed (in example "Copacabana beach Brazil") and set dimensions (width and height) of the map. That's it. Your map is ready! There's not need to register or copy any code.
