    Haven’t read details, but the classic way is to have a system visit: site.com/badimage.gif?data=abcd

    Note: That s is also how things like email open rates are tracked, and how marketers grab info using JavaScript to craft image URLs.

      This is why every single email client for the past 2+ decades blocks external images? This didn’t occur to the AI geniuses?

        IME they usually proxy and/or prefetch images for caching instead of blocking them. Only spam content is blocked by default.

          This wouldn’t help, would it? How would you prefetch and cache:

          site.com/base64u-to-niceware-word-array/image.gif

          ? It would look like a normal image URL in any article, but actually represent data.

          Note: “niceware” is a way to convert binary or text data into a set of words like “cow-heart-running-something-etc”.
