title: How to select an image from internal storage and insert it in SQLite?
body: <p>When the user clicks a button in my app, he has to be able to select an image from the internal storage (sd card or tablet/phone memory). Then, I want this image to be stored in a SQLite database.</p>
  
  <p>So there is three questions:</p>
  
  <ul>
  <li>How can I show the gallery or the file explorer to the user, so he can navigate and select an image?</li>
  <li>How will the app know which image was selected?</li>
  <li>How can my app store the image in a database (BLOB data)? </li>
  </ul>
