How to insert image using SQLite plugin?

Hi I am trying to insert a image into sqlite database.I am using cordova,html and jquery. I tried reading image using filereader with readAsUrl which gives me base64 format of image. I am struck with storing this image. This code works fine,

var file  = document.querySelector('input[type=file]').files[0];

  var reader  = new FileReader();


  reader.onloadend = function () {
img = reader.result;
    if(file.type.match('image.*'))
    {
    img = reader.result;
    console.log(img);
}
else
{
  alert("select an image file");
}
  }

  if (file) {
    reader.readAsBinaryString(file);
    var objectURL = URL.createObjectURL(reader.result);
imagess = objectURL;
console.log(objectURL);

  } else {
    preview.src = "";
  }

Using this above code I am able to get image as base64 format and when I set this as image source I could see the image in my browser. Can someone please help me?
