My images are hosted on parse and my mobile app shares to twitter. It is my hope that cards will be generated from the share and they contain all the right tags. For some reason, however, the image will not show up for media hosted at http://files.parsetfss.com.
Original link (with your images): https://dl.dropboxusercontent.com/u/13158636/site/twitter%20cards/test-1-original.html
Link with different images that for some reason Twitter doesn’t block: https://dl.dropboxusercontent.com/u/13158636/site/twitter%20cards/test-2-butterfly.html
Anyone know a reason why the og:image is not displaying in card validator? I know facebook owns parse but not sure if twitter would blacklist this type of link for some reason. Any help us much appreciated. Thank you.
