Ok, so while the image uploads are working, the image loading isn't working. The images are hosted on Amazon AWS S3 and their SSL certificate is broken for some reason.
Hang in there, it should resolve itself. In the meanwhile, you can do this to see images:
- Right-click an image (or where you know there should be an image).
- Open it in a new tab.
- When you get a notice that it's not secure, click to ignore that (or whatever the option is).
That should make all forum images work for you for now. (And when Amazon fixes things on their side, images will still work fine for you 🙂
