I’ve been seeing that more and more. I’ve been replacing them with files I’ve downloaded to my own system and then reuploaded, or replacing them by ‘fetching’ a new copy from Twitter, so I’m not making any change to the files - it’s just that sometimes they don’t work, then the next time they do, and I don’t see anything that I’m doing differently from what you are doing.
And the same is happening from DeviantArt as well.
I haven’t been able to find a pattern. Sometimes three uploads by the same person from the same gallery will work, fail, work. Usually just ‘refetching’ the middle donked image makes it work, and I haven’t been able to find any meaningful difference between the three images.
What ever it is, it doesn’t appear to be something we can replicate on demand.
At the least, I try to make sure anything that comes through the queue both loads and has thumbnails, etc. But if the uploader didn’t provide a source then sometimes there’s nothing I can do except ‘hope it works eventually’.

If one of your uploads is donked, please report it for a reason of ‘other’ and ask us to fix it. As long as there’s a source we can get at, we’ll be able to get it to load. But sometimes we have to try two or more different ways of getting it up to the site before it will work.
