I did this: I have the Yoast plugin on my site and clicked to use the social 'twitter card meta data' to help improve the visibility of my tweets. I then verified my page with Twitter which was accepted.
I expected the plugin to do this: to include the title, description and image of my content when posted on twitter.
Instead it did this: it only included the title and description of my content but didn't implement the image code. I have no idea why it did this? Is the plugin by Yoast meant to include this? is anyone else having the same problems?
