Code works in the real world - fails in the emulator

Question

If you want to test this try http://hatemytory.com/java/deploy.wml
Anyway, my code loads an image over the network using http. This (appears) to work fine in the real world but in the WTK emulator it chokes by only downloading the first 16358 bytes of the image and then failing on the createImage call.
Apologies for the code being a bit choppy - I've been fiddling with it to see why it might fail - is this me or is it the WTK?
private void loadToryImage()throws IOException {
          HttpConnection hc = null;
          DataInputStream in = null;
          String torylist = null;
          byte[] data = null;
          int index = 0;
          int length = 0;
          try {
               String baseurl =
               "http://hatemytory.com/tory-cgi/getpngtory.pl?name=";
               String word = mTory.replace(' ', '+');
               String coords = "&x=" + x_width + "&y=" + y_height;
               String url = baseurl + word + coords;
               hc = (HttpConnection) Connector.open(url);
               length = (int)hc.getLength();
               if (length != -1) {
                    data = new byte[length];
                    in = new DataInputStream(hc.openInputStream());
                    in.readFully(data);
               else {
                    //read in in chunks
                    int chunkSize = 0;
                    int readLength = 0;
                    in = new DataInputStream(hc.openInputStream());
                    chunkSize = (int)hc.getLength();
                    data = new byte[chunkSize];
                    do {
                         if (data.length < index + chunkSize) {
                              byte[] newData = new byte[index + chunkSize];
                              System.arraycopy(data, 0, newData, 0, data.length);
                              data = newData;
                         readLength = in.read(data, index, chunkSize);
                         index += readLength;
                    }while (readLength == chunkSize);
                    length = index;
               logo = Image.createImage(data, 0, length);
          catch (IOException ioe) {
               logo = null;
               return;
          finally {
               if (in != null) in.close();
               if (hc != null) hc.close();
          return;
