act on the twitter_cards_properties filter. see FAQ for an example; you’ll want to act on image values instead of creator values given in the FAQ.
Niall, I don’t know what you mean by “act on” the filter? Does that mean replace the ‘creator’ fields or to add the ‘twitter:image’ to what’s already there? And if I wanted the Twitter card to be an Image_large_summary, what would I do, specifically? What code do I add, replace and/or delete?
Many thanks,

The WordPress documentation has more information about how to customize WordPress and plugin defaults using filters.

This should be easier / automated… having to code isnt really an easy way to use a plugin. Other than that everything else is good.
