    Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.f1);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] food = stream.toByteArray();
        Intent intent = new Intent(MainActivity.this,NoBoringActionBarActivity.class);
        intent.putExtras(bundle);
        intent.putExtra("picture", food);
        startActivity(intent);  
    

    Sending Activity

    Bundle extras = getIntent().getExtras();
    
    
        byte[] food = extras.getByteArray("picture");
        Bitmap fo = BitmapFactory.decodeByteArray(food, 0, food.length);
        mHeaderLogo = (ImageView) findViewById(R.id.header_logo);
        //ImageView image = (ImageView) findViewById(R.id.header_logo);
        mHeaderLogo.setImageBitmap(fo);   
    

    Receiving Activity

    Don't forget to place your image in drawable.

    You can use a global class with a static bitmap object in it, something like this:

    public class Global { static Bitmap img; }

    Before stating the activity by intent, assign your bitmap to this Global class attribute:

    Global.img = your_bitmap_img;

    After starting your activity, you can get back your bitmap by:

    bitmap_in_new_activity = Global.img;

    I know global variables are too dangerous for debugging but this technique helps us to transfer large data from one activity to another.The binder transaction buffer has a limited fixed size, currently 1Mb regardless of your device capabilities or your app.
