Is that link tor-hostile? I just get a blank page (which is expected since I have images disabled). But then I ran:
torsocks curl -I https://midwest.social/pictrs/image/4f02113b-f999-4992-bb9c-93ecc9470bd8.png
to get the image size, and got zero:
HTTP/2 405
server: nginx
date: Sun, 08 Oct 2023 12:43:23 GMT
content-length: 0
vary: Origin, Access-Control-Request-Method, Access-Control-Request-Headers
allow: GET
access-control-expose-headers: allow
What happens if you use cURL? The link you just posted has the same problem for me (same host).
