Pic.twitter url not rendering as image


Hi, I have gone through the effort of getting my Twitter API implementation uploading an image, tweeting it, and returning the tweet data with media_urls. However, when creating a tweet with pic.twitter.com/xxxx in the body -it doesn’t render as an image in their tweet.

Is there any way to give the user a url for an image which they can tweet, without forcing them to authorize my app and post for them? Besides having the image in my tags. Which I can’t do because of the nature of our SPA site.
