title: Delphi: How to tag photos the way facebook does
body: <p>I need a way to tag photos in a Delphi desktop application the way Facebook does it. </p>
  
  <p>That includes some way to easily add the tags over the people, and then hovering the mouse over the person in the photo to show the tag.</p>
  
  <p>The two suggestions in the answer given to: "<a href="https://stackoverflow.com/questions/431086/delphi-components-for-face-identification-and-tagging">Delphi Components for Face Identification and Tagging</a>" don't solve this.</p>
  
  <p>But I have no idea where to start, and have been unable to find ideas on the web on how to do this. How does Facebook do it? Or maybe there's a component for Delphi that will allow it. </p>
  
  <p>What would be the best way to try to implement Facebook-like tagging?</p>

  <p>p.s. This is some of Facebook's API definition for this: <a href="http://wiki.developers.facebook.com/index.php/Photos.addTag" rel="nofollow noreferrer">http://wiki.developers.facebook.com/index.php/Photos.addTag</a></p>
  
  <p>Here is a Java program that implements the face tagging functionality that I want to do in my Delphi app: <a href="http://code.google.com/p/fb-photo-uploader/" rel="nofollow noreferrer">fb-photo-uploader</a></p>
