When I use this earth file ,the mimetype is "image/jpeg; charset=utf8",in file HttpClient.cpp,line 1522,so the function "osgDB::Registry::instance()->getReaderWriterForMimeType(mimeType)" returns NULL,then I get a blank ball. The mimetype in HTTPResponse class actually is Content-Type ,not Mimetype

I believe this is actually a server problem. It does not make sense to append a charset for a binary mime type like image/jpeg.
