2 ways to refresh theTwitter Card Image ( how to force cache purge of TwitterBot/1.0 )

In order to refresh the Twitter Card, Twitter says that we just add an extra parameter at the end of your image URL ( My Card information now refreshes, but images are not updating. How do I get the images to refresh? ).

And according to this page ( https://stackoverflow.com/questions/28207497/how-to-force-cache-purge-of-twitter-cards-bots ), we can update it by using Twitter Card Validator without adding an extra parameter.
