Thumbnails in post teaser
Previously the images were loaded but not shown - we had that fixed as a bug, but it seems someone at NodeBB decided they want thumbnails instead. Except, for most images they're almost useless:
It's still just the original image shrunk with CSS, so the download size is still the same.
If a few post have large images then the download size for the front page becomes silly. When I reported the original bug, I'd seen the front page download 80MB of images
Until the next time it's unfixed...
