This plugin by Rich Gubby makes it easy for a webmaster’s to embed Microsoft Bing Maps in a blog post.
You don’t have to worry about how the maps are displayed, the plugin takes care of that. You can create dynamic maps that allow your visitors to pan and zoom, or static maps that don’t have those features. You can create Road maps, Aerial views, Aerial views with roads marked on them, or even a 3D Birdseye view.
The plugin uses [bingMap] shortcodes.
