Single Image url

Hi,

Exactly as meta tag was; https://www.drupal.org/node/1305402#comment-6420040 → , the Image url token gives an array of image url's when there are more than one image in the image field.
Is it possible to add a token to get only the first image url in the image field url token?

Thanks a lot in advance for considering this.
greetings, Martijn
