javascript - How can I tell if Google's Streetview Image API Returns "Sorry, we have no imagery here" (ie. NULL) Result?

Question

The Google Street View Image API lets you embed a static (non-interactive) Street View panorama or thumbnail into your web page, without the use of JavaScript.

Request URL: http://maps.googleapis.com/maps/api/streetview?parameters

+The Problem+

If I give it an address for which it doesn't have a Streetview, it returns an image that says, "Sorry, we have no imagery here".

Based on the current API, I have no way of detecting if it found a Streetview or not. Anyone have a hack or suggestion for figuring this out?

+Examples+

Proper Streetview: http://maps.googleapis.com/maps/api/streetview?size=300x300&sensor=false&location=100+Highland+Ave+Baltimore,+MD+21224

Sorry Streetview: http://maps.googleapis.com/maps/api/streetview?size=300x300&sensor=false&location=1600+Pennsylvania+Ave,+Washington,+DC+20500

Consider using StreetViewService and StreetViewStatus objects in Google Maps: https://developers.google.com/maps/documentation/javascript/streetview#StreetViewService

Essentially what you'll have to do is create a StreetViewService object that will try to find a panorama based on location, using the getPanoramaByLocation(latlng:LatLng, radius:number, callback:function(StreetViewPanoramaData, StreetViewStatus)) method.

In the callback function, have a conditional argument that will check for the data availability if (status == google.maps.StreetViewStatus.OK). Based on the boolean return, execute the desired actions. The first link I provided got a great example of the use of these methods.

Note: I also notice you've got locations based on addresses. This can be simply converted to LatLng using the Geocoding Service ( https://developers.google.com/maps/documentation/javascript/geocoding )
