Using Bing imagery
Bing Maps, previously known as Virtual Earth, is the mapping service provided by Microsoft.
In the same way as Google Maps, OpenLayers offers an OpenLayers.Layer.Bing
class, which brings us the possibility to add Bing imagery in our projects.
Getting ready
Bing Maps requires you to register as a consumer user. Once registered, you will get an API key needed to initialize the OpenLayers.Layer.Bing
layer and that will be used with every request to authenticate you against the Bing Maps service.
Opposite to Google Maps, Bing does not require any JavaScript code and the OpenLayers.Layer.Bing
class does not act as a wrapper. Bing Maps offer a REST service to directly access tiles using your API key.

At this point, it is assumed that you have an API key to be used...
