Image not inserting in sqlite database android

Anyone Please Help me. I am trying to create a dictionary application in which i want to save words ,their meanings and picture with every word. I am trying to save all the words,images and meanings in sqlite database. The problem is that when i click on any word in the listview it shows me the word and definition but the image field is blank.Here is my class in which i am creating my database.

    public class DictionaryDataBase extends SQLiteOpenHelper {


    byte[][] img = {
            DbBitmapUtility.getBytes(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher)),
            DbBitmapUtility.getBytes(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher)),
            DbBitmapUtility
                    .getBytes(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher)) };

    public DictionaryDataBase(Context context) {

        super(context, DATABASE_NAME, null, 1);

    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL(
                "CREATE TABLE Dict_Table (id INTEGER PRIMARY KEY, word TEXT NOT NULL, definition TEXT NOT NULL, image BLOB NOT NULL);");
        try {

            new DictionaryDB(context).addEntry(words, def, db, img);
        } catch (Exception e) {
            Log.e("Error", e.toString());
        }

    }

and this is the add entry method:

   public void addEntry(String[] word, String[] def, SQLiteDatabase db, byte[][] img) throws SQLiteException {
    for (int i = 0; i < word.length; i++) {
        db.execSQL("INSERT INTO Dict_Table VALUES (" + i + 1 + ", '" + word[i] + "', '" + def[i] + "', '" + img[i]
                + "');");
    }

and this is the method which i am using to get the image:

    public byte[] Getimage() throws SQLException {
    dbhelper = new DictionaryDataBase(context);
    SQLiteDatabase db = dbhelper.getReadableDatabase();

    Cursor res = db.rawQuery("SELECT * FROM Dict_Table WHERE word='" + MainActivity.item + "'", null);//MainActivity.item is the item which was clicked in the list view
    res.moveToFirst();
    byte[] img = res.getBlob(res.getColumnIndex(IMG_COL));
    if (!res.isClosed()) {
        res.close();
    }
    return img;

}

DbBitmapUtility.java:

   public class DbBitmapUtility {

// convert from bitmap to byte array
public static byte[] getBytes(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.PNG, 0, stream);
    return stream.toByteArray();
}

// convert from byte array to bitmap
public static Bitmap getImage(byte[] image) {
    return BitmapFactory.decodeByteArray(image, 0, image.length);
}

}

If you need any other information I will provide it to you but please help me in this case. Its since 2-3 days, I have been stuck here.
