It depends on how you want to store your Image, because you are storing as a byte array here is how to retrieve it

  public Cursor fetchAll() {
            return databaseHelper.query(ITEMS_TABLE, new String[] { COLUMN_ITEM_ID,   COLUMN_ITEM_NAME, COLUMN_ITEM_SPECS,COLUMN_ITEM_PRICE, COLUMN_ITEM_IMAGE,COLUMN_ITEM_QTY},null, null, null, null, null);
        }
/*    this method will give you a cursor with all the records of your database table now you need to parse these records on to objects*/

private List parse(Cursor cursor) {
     List toReturn = null;
     toReturn = new ArrayList();
     ItemsPojo obj;
     if (cursor.moveToFirst()) {
          while (cursor.isAfterLast() == false) {
               obj = new ItemsPojo();
               obj.setId(cursor.getInt(0));
               obj.setItemName(cursor.getString(1));
               obj.setItemSpecs(cursor.getString(2));
               obj.setItemPrice(cursor.getDouble(3));
               obj.setItemImg(cursor.getBlob(4));
               obj.setItemQuantity(cursor.getInt(5));
               toReturn.add(obj);
               cursor.moveToNext();
               }
     }return toReturn;
}

now you have a List with all your records on your database, now what you need to do is create a ListActivity and show all your objects on it, If you dont know how to do this please post your comment here or if you have any doubt about the procedure above
