How JPG or GIF Image open in MIDP?

Question

How my j2me application can support jpg or gif image format. I have tested png file in midp 1.0 and its not support other than png format( im not sure about midp 2.0 does it support or not). I have seen lot of mobiles those support gif and jpg file formats. Does j2me applications on those mobile can support other image formats?
Plus it is possible that i can develop my own decoder for jpg or gif format. I know it possible, but im talking related to its processing power consumption. Or is there any third party api exist to support jpg or gif file format on midp. Please r

Here is the code snap that read image from a URL.. I have tested this code on localhost & two different pc on lan in emulator.. but not in actuall mobile... but i hope it will work...
Image image = null ;
DataInputStream httpInput = null ;
DataOutputStream httpOutput = null ;
HttpConnection httpCon = null ;
String url = "http://localhost:8080/images/picture.png"
try
httpCon = (HttpConnection)Connector.open(url);
int bufferSize = 512 ;
     byte byteInput[] = new byte[bufferSize] ;
     ByteArrayOutputStream imageBuffer = new ByteArrayOutputStream(1024*50);
     httpInput = new DataInputStream( httpCon.openInputStream() );
               System.out.println("Http-Input Connecting Establish Successfully");
               httpOutput = new DataOutputStream( httpCon.openOutputStream() );
               System.out.println("Http-Output Establish Successfully");
int size = 0 ;
// read all image data ....
     while ( ( size = httpInput.read( byteInput , 0 , bufferSize ) ) != -1 )
                    imageBuffer.write( byteInput , 0 , size ) ;
// get byte from buffer stream
          byte byteImage[] = imageBuffer.toByteArray();
               System.out.println("read byte " + byteImage.length );
     // convert byte to image ...
     image = Image.createImage( byteImage , 0 , byteImage.length );
     return image ;
     //return null ;
catch( IOException e )
               System.out.println("\nUnable to Perform Image IO Operation with Host");
     return null ;
