AstonishingRabbit13 If I'm not mistaken, you can add images to the preview tab by reporting them as debug samples.

So you'd run: dataset.get_logger().report_image() or report_media()
This is not scalable though, so don't expect the server to handle millions of images well, for that you'd need Hyperdatasets 🙂
But it works well (as the name suggests) for some previews of the images!
