I have studied the Twitter Cards but wish to learn if Twitter Cards can be amended to work as follows:
Please see https://twitter.com/Earth_Pics - is it possible to adjust the Twitter Cards so that they can automatically pick up pictures from a XenForo discussion forum and put them on a Twitter account’s main page/feed (automatically) such as @Earth_Pics? Can this be done?
(The aim is not to have to put in pictures into a Twitter account manually like done at https://twitter.com/Earth_Pics).
Or, is there any add-on which can do this?
