No the image host changes post is from 2018. The issue today is that the SSL Cert for attachments.f95zone.com expired. I'm sure the devs will fix it as soon as they have a chance.
Try open any random attached image in your new tab or just use this one and when you found the "Your connection is not private" screen, click on the [Advanced] and click the proceed to attachments.f95zone.to (unsafe) at the bottom. That would open the image.
Now go find random thread on this site and see if their images load or not. If not, clear your browser's cache and reload the site.
Do it at your own risk or wait until admin fix the SSL certificate.
