DATA_URL	number	0	Return base64 encoded string. DATA_URL can be very memory intensive and cause app crashes or out of memory errors. Use FILE_URI or NATIVE_URI if possible
FILE_URI	number	1	Return file uri (content://media/external/images/media/2 for Android)
NATIVE_URI	number	2	Return native uri (eg. asset-library://... for iOS)
