title: What is an "IFD size"?
body: <p>What does IFD mean?</p>
  
  <p>I have a error message in my application when I upload an image:</p>
  
  <blockquote>
    <p>PHP message: PHP Warning:  exif_read_data(upload_file123): Illegal
    IFD size in
    /srv/www/path/to/my/vendor/gregwar/image/Gregwar/Image/Adapter/Common.php
    on line 102</p>
  </blockquote>
  
  <p>What does this mean? I tried to search in Google, but I couldn’t find what IFD means.</p>
  
  <p>What might be the causes of this error?</p>
