Great, ... so there's now Youtube embeds on SN Posts, along with the earlier Twitter embeds.

But I can't post a .jpg or .png and have the image displayed when someone clicks the post. I have to do instead a Discussion post and then use image markdown (! [name] (URL) ) in order to get close enough to what image rendering for an image post would appear as.

Doing it with markdown instead is not a big deal, but then the Twitter Summary (or whatever they call it) doesn't display the image. For example, the Twitter Cards validator shows that SN Item #10459 will look like this:

.

So anyone including the link to the post in Twitter (and on Mastodon), doesn't get the image in the rendering of the post.

I suppose there are reasons for concern, ... a person could create a post with porn or something along those lines, and boost it, and that image will appear on the StackerNewsFeed accounts on Twitter and Mastodon as it ends up on the front page, and thus those following those accounts will see the image the person posted on SN, unfiltered (beyond what the SN WoT algo determines).
