New WordPress plugin to render a map with multiple markers using the open source maps provider OpenStreetMap
A friend of mine ask me to install my MultiMarkersOnGmap on hist site, but he hasn't a key or any knowledgement about how to get a Google Maps key, so the only solution was modify that plugin and use the great and free OpenStreetMap API alternative.
The only thing you need to run this awesome plugin in your own WordPress site is, besides install it, to add a shortcode wherever you want and define some markers:
(PS: As I mentioned before, this is a clone of https://github.com/oscaralderete/multiple-markers-on-google-maps, so if you find any bug, please, let me know to fix it. Apparently work fine, but who knows!)
