  <p>index.php prints messages / images uploaded via admin.php <br>
  admin.php is for submiting data / images so that way can be shown on index.php <br>
  upload.php is called when the submit button is pressed on admin.php <br></p>
  
  <p>Question: I need to modify upload.php to somehow put an ID on every uploaded image so it can be printed on index.php using its ID, How should it be?</p>
