    // setType("image/png"); OR for jpeg: setType("image/jpeg"); 
    share.setType("image/*"); 

    // Make sure you put example png image named myImage.png in your 
    // directory 
    String imagePath = Environment.getExternalStorageDirectory() 
      + "/myImage.png"; 

    File imageFileToShare = new File(imagePath); 

    Uri uri = Uri.fromFile(imageFileToShare); 
    share.putExtra(Intent.EXTRA_STREAM, uri); 

    startActivity(Intent.createChooser(share, "Share Image!"));
