BGMP creates a custom post type for placemarks (markers) on a Google Map. The map is embedded into pages or posts using a shortcode, and there are settings to affect how it's displayed. Then you can create markers that will show up on the map using the featured image as the map icon. When a marker is clicked on, a box will appear showing its title and description.

Features

• Each map marker can have a unique custom icon, share a common custom icon, or use the default icon.
• Options to set the map type (street, satellite, etc), center location, size, zoom level, navigation controls, etc.
• Setup unique maps on different pages with their own placemarks, map types, center locations, etc.
• Placemarks can be assigned to categories, and you can control which categories are displayed on a individual map.
• Marker clustering for large numbers of placemarks
• Extra shortcode to output a text-based list of markers for mobile devices, search engines, etc.
• Lots of filters so that developers can customize and extend the plugin.
• Use HTML, images, etc inside the information window.
• Compatible with WordPress MultiSite.
• Internationalized (see Other Notes for a list of supported languages)

You can see live examples of the plugin running at the Australian Polio Register, the North Carolina Fire Station Mapping Project and Washington House Churches.

Instructions are on the Installation page, and the FAQ has a lot of documentation and troubleshooting resources.
