Google has stopped giving out news keys for the Google Maps Flash API (please see the appropriate thread for details), so a replacement/alternative was necessary and now here is one in form of the krpano Bing Maps Plugin .
The krpano Bing Maps Plugin uses the same interfaces as the krpano Google Maps Plugin. That means for switching from the Google Maps to the Bing Maps just replace the googlemaps.swf by the bingmaps.swf and change in the xml the Google Maps key by the Bing Maps key.
A key for Bing Maps can be requested here:
The krpano Google Maps Plugin License itself will be of course also valid for the krpano Bing Maps plugin - just rename the googlemaps.license.xml to bingmaps.license.xml.
The Bing Maps Plugin is included in the normal krpano download packages:
The plugin documentation:
And here a small demo with a comparison between the Bing Maps Plugin (on the left side) and the Google Maps Plugin (on the right side):
The two maps plugins in the demo were synced by xml code, here the xml of the demo if interested:
Some technical details about the Bing Maps Plugin:
The plugin is based on the open-source OpenScales Flash API. In some details the map rendering is not that good as in the Google Maps Plugin, so I will still try to improve the one of other thing, but generally it is already working really well.
