bmp = BitmapFactory.decodeFile("/sdcard/GWonderPhoto/"+s+".jpg");

change this line to:

bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory()+"/GWonderPhoto/"+s+".jpg");

EDIT

also see if following permissions are added in Manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

i hope this will help you.

use

setContentView(R.layout.photoeffect_1);

just after 

super.onCreate(savedInstanceState);

i.e. rewrite onCreate method as

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
 // TODO Auto-generated method stub
    setContentView(R.layout.photoeffect_1);
    Intent i = this.getIntent();
    String s = i.getStringExtra("second");
    Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();

    bmp = BitmapFactory.decodeFile("/sdcard/GWonderPhoto/"+s+".jpg");
    img = (ImageView) findViewById(R.id.imageView1);
    img.setImageBitmap(bmp);
}
