In my web page where the player is hosted, I specified twitter:image as https://s3-ap-southeast-2.amazonaws.com/mi9-video-new-player-dev/imgs/video-thumnail.jpg.
However, after I shared that page on Twitter, what I see at the location where the image is normally expected to appear is a totally unrelated image with title " Mixture Photos". When clicking the image, it brings me to https://twitter.com/mixturephotos, which I have no idea about.
The tweet in question can be found at https://twitter.com/xwk4g_xwk/status/635710211978756097
Is that a bug of Twitter?
