A great intro to this plugin

This is a great, basic plugin that lets you easily add Google Maps to your site with a simple shortcode, but also adds additional useful features. I personally needed photos on my map, and this plugin let’s you add an entire gallery of photos on each location, as well as a video. Then of course is the image mode, which renders the map in a really cool Google-like tile set with lots of zoom levels that all look crisp and clear. It really sells the illusion that the image map is just like a Google map. Neat.
