Hello,
You haven’t provided the exact URL you are referring to so I’ve picked one of the articles: https://www.batimes.com/articles/what-about-the-current-state.html
This page doesn’t contain the twitter:image meta tag (it only contains og:image), I would suggest adding it.
The Image provided in the og:image is with low quality (200 × 100) so might get pixeled if re-sized.
You should add an image with the following:
Images for this Card support an aspect ratio of 2:1 with minimum dimensions of 300x157 or maximum of 4096x4096 pixels. Images must be less than 5MB in size.
more details can be found here: https://developer.twitter.com/en/docs/tweets/optimize-with-cards/overview/summary-card-with-large-image
