I just thought I try to create a new post with a picture.
On New, it only offers me a URL option (no upload)
On Old, it says:
Post "https://./pictrs/image": dial tcp: lookup . on 10.43.0.10:53: no such host. there doesn't seem to be anything here
It'll let me do if I just go the endlesstalk.org (no frontend) though. This was what I was testing.
It's on New that I'd really like to be able to use to do it though.
