I thought that images uploaded through the editor (and consequently using SE imgur account) should be permanent. Is it just me, or are the images from this post really gone?

I mean they can be still saved from Wayback Machine and I might have them even somewhere on my computer - I have probably saved them when I was posting the question.

I am just surprised that hey are gone. (At least that is how the post looks to me.)

And now after I come to complain here, I refreshed the page again and I see them again. Probably just a glitch. So ignore the above messages.

It seems that I was too hasty to report a problem which - as it turned out - was not really a problem.
