Passing Images between Activities in Android

in First Activity:

    Intent intent=new Intent(FirstClass.this, SecondClass.class);
    Bundle bundle=new Bundle();
    bundle.putInt("image",R.drawable.ic_launcher);
    intent.putExtras(bundle);
    startActivity(intent);

in Second Acticity:

    Bundle bundle=this.getIntent().getExtras();
    int pic=bundle.getInt("image");
    v.setImageResource(pic);

another method:
in First Activity:

    Drawable drawable=imgv.getDrawable();
    Bitmap bitmap= ((BitmapDrawable)drawable).getBitmap();
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
    byte[] b = baos.toByteArray();
    Intent intent=new Intent(Passimage.this,myclass.class);
    intent.putExtra("picture", b);
    startActivity(intent);

in Second Acticity:

   Bundle extras = getIntent().getExtras();
   byte[] b = extras.getByteArray("picture");
   Bitmap bmp = BitmapFactory.decodeByteArray(b, 0, b.length);
   ImageView image = (ImageView) findViewById(R.id.imageView1);
   image.setImageBitmap(bmp);
