How to add image directlty to sqlite database, using BLOB statement

I have created an Android App, which adds questions to a SQLite database, and then displays them to the user using Radio Buttons and Strings.

This works OK -but now I want to add an image into the database directly, uisng a BLOB key. What is the syntax/path to use in the AddQuestions method, as below?? In other words, what should I enter for the final text/src in the question??

Thanks in advance!

private static final int DATABASE_VERSION = 1;
    // Database Name
    private static final String DATABASE_NAME = "triviaQuiz";
    // tasks table name
    private static final String TABLE_QUEST = "quest";
    // tasks Table Columns names
    private static final String KEY_ID = "id";
    private static final String KEY_QUES = "question";
    private static final String KEY_ANSWER = "answer"; //correct option
    private static final String KEY_OPTA= "opta"; //option a
    private static final String KEY_OPTB= "optb"; //option b
    private static final String KEY_OPTC= "optc"; //option c
    private static final String KEY_IMAGE_DATA= "image_data";
    private SQLiteDatabase dbase;
    public DbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }
    @Override
    public void onCreate(SQLiteDatabase db) {
        dbase=db;
        String sql = "CREATE TABLE IF NOT EXISTS " + TABLE_QUEST + " ( "
                + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_QUES
                + " TEXT, " + KEY_ANSWER+ " TEXT, "+KEY_OPTA+" TEXT, "
                +KEY_OPTB+" TEXT, "+KEY_OPTC+" TEXT, "+KEY_IMAGE_DATA+" BLOB not null)";
        db.execSQL(sql);
        addQuestions();
//db.close();
    }
    private void addQuestions()
    {
        Question q1;
        q1 = new Question("Which company is the largest manufacturer" +
                " of network equipment?","HP", "IBM", "CISCO", "C", src="src/main/res/drawable-hdpi/harbour1.png");
        this.addQuestion(q1);
        Question q2=new Question("Which of the following is NOT " +
                "an operating system?", "SuSe", "BIOS", "DOS", "B");
        this.addQuestion(q2);
        Question q3=new Question("Which of the following is the fastest" +
                " writable memory?","RAM", "FLASH","Register","C");
        this.addQuestion(q3);
        Question q4=new Question("Which of the following device" +
                " regulates internet traffic?",    "Router", "Bridge", "Hub","A");
        this.addQuestion(q4);
        Question q5=new Question("Which of the following is NOT an" +
                " interpreted language?","Ruby","Python","BASIC","C");
        this.addQuestion(q5);
    }
