Can't see embedded pics from one poster

[freespool]

I'm never able to see embedded pics from one poster. Instead I see a tiny icon that looks like a page or piece of paper. I know there are embedded pics because I can follow the pic link in the notification email. It just doesn't show up if I instead go to the forum post. I can see pics from any other posters, just not this one guy. The pics tend to be the sole content of his post, but I can't say for sure it's always like that. Using Firefox.

Anyone know what's going on?

...let the wicked be put to shame...

Update: if I use MS Edge, the pics show up. It must be something unique about the way his inline pics are coded, that Firefox doesn't like.
