I was looking for a simple tool to create imagemaps of the USA so that I could have my customers click on various states, and find our products in their states. This tool fit the bill very nicely! It is easy to do massive updates with the export/import capability, which allows you to update a CSV file and then upload it to the Joomla site. It took me 5 minutes to get it up and running.
I did run into one minor problem with jQuery not working properly, but when I emailed the support, within 4 hours, they answered my question and my site is working great!
I am very pleased with this tool!
