The missing images seems to be something with the backend S3 storage of the forum, the images have either gone missing or the permissions have changed.
@ChrisGammell, you will probably want to look into this and check on the forum hosting because this could be a problem if we’re going to have images in posts go missing.
Have you been seeing this on multiple posts? Could you post examples here? I wanted to make sure I split out this issue from the build log.
So it seems like new pictures are ok. Was it just @jonthomasson’s posts? Anyone seen this elsewhere?
Hey @ChrisGammell, I’m not sure if it’s related or not, but I noticed one of the pics Matt posted on his build log today is missing: Matt’s Build Log. Then in the Building out your Lab discussion, the pic I posted of the storage shelving is missing: Building out your lab. It seems like they were showing for a little while, and then just vanished. I noticed at least with the picture I posted it’s throwing an “Access Denied” error from the web service.
Yes, like @jonthomasson mentioned the picture that Matt posted went missing very quickly, the ones that Jon posted took a few days. I had some images cached, but when I cleared my cache they were gone and I would get “Failed to load resource: the server responded with a status of 403 (Forbidden)” in the browser console and “Access Denied” from the S3 bucket.
BTW, @algoritaville’s build log starts off mentioning he’s in IT, maybe can trade services there 
Mine was saying that yesterday but now it appears if you click the image it’s back, just isn’t showing the preview any longer.
I took another look at this and it looks like you’re right the actual image is there, but the preview/optimized version is broken. It isn’t showing access denied or forbidden for the preview, it is actually responding with an ‘OK’ 0 byte response:
curl -v 'https://ce-forum.s3.amazonaws.com/optimized/1X/51fb2a7eb1deb7b2993cf5c5b9023b056cf177ce_1_666x500.jpg' -H 'Pragma: no-cache' -H 'DNT: 1' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: en-GB,en-US;q=0.8,en;q=0.6' 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8' -H 'Cache-Control: no-cache' -H 'Connection: keep-alive' --compressed
responds with:

It would be interesting to see if there is a file in the S3 bucket that is 0 bytes, or if it is missing but the server is responding with OK even though there is no data.
Since we haven’t seen any issues since, I’m going to close this topic. I am guessing there was a blip when the images were uploaded. If people are very concerned, I would recommend downloading the image and trying uploading again. I realize this isn’t an optimal solution, but it seems limited in scope to not worry too much right now. If people see it happen again, please let me know ASAP.
