title: Storing Image Thumbnail INTO Image in Android
body: <p>I am implementing a gallery of images that are stored in a folder in the SD card. The images are copied from the server. I am trying to display thumbnails using the Interface <code>ExifInterface</code>. It has a very nice method <code>getThumbnail</code>. This method returns a thumbnail if it exists or null if not. But the condition is that the image NEEDS to contain the thumbnail WITHIN. </p>
  
  <p>My Question is: How can I create a thumbnail INSIDE the image when I save the image to SD card so that <code>ExifInterface.getThumbnail</code> detects that thumb and does not return <code>null</code></p>
