  <p>The error shows:</p>
  
  <blockquote>
    <p>no mapping exists from object type</p>
  </blockquote>
  
  <p>Is it because my convert image is wrong?
  Or is there another way to update the image to my sql?
  The thing is I need to update my values in the image which I can display and update which can save to my database.  </p>
