There is a known issue with the photos in older posts not loading.

Short answer just click the old link and the photo will load.

Basically when the site was migrated over last year we enabled the HTTPS more secure page, from just the HTTP.

When I did the WebP uptick a few weeks back I noticed there were some older posts that would not load the photo in the post view, but when clicked it loaded just fine. In general there were other issues to deal with and went back and forth on the WebP and some other issues, figure would get back to it eventually.

I can see the issue and will work to fix it, basically the old post is call it, hard coded to the HTTP image link and the WebP stuff does not load those, so will work on a fix to change over the HTTP:// stuff to HTTPS:// stuff, I did a fix for something like this early on, Dave helped me get the photos loading on relaunch and I feel its a similar fix, that was change upload2 to just upload on like 60k posts and it was super fast to do that and also super fast to break it, but need to do some work on getting back to that.
