Image with no thumbnail

When I uploaded post #157394, it didn't generate any thumbnail. I was wondering if it's a broken JPEG file. It came from http://harukayume.sakura.ne.jp/2007_07.html

Try uploading it again.

It works now. Thanks.

So it seems. Strange indeed, I uploaded it through danbooruup like I've done thousands of times before. I'd delete and reupload but the hash wouldn't be free and I wouldn't be able to add it again.

post #160564 also seems to suffer from thumbnail-anemia. Is there anything these posts have in common?

I've manually repaired these two.
