				&#xd;&#xd;The CameraRoll.addBitmapData() method adds an image to the device's dedicated media library. To check at run time whether your application supports the CameraRoll.addBitmapData() method, check the CameraRoll.supportsAddBitmapData property.
				&#xd;&#xd;The CameraRoll.browseForImage() method opens an image-choosing dialog that allows a user to choose an image in the media library. When the user selects an image, the CameraRoll object dispatches a select event. Use the MediaEvent object dispatched for this event to access the chosen image. To check at run time whether your application supports the CameraRoll.browseForImage() method, check the CameraRoll.supportsBrowseForImage property."/>
