More and more images go missing. Can the cooked HTML be rebuilt?

But that's not what the actual HTML source code of the question shows!

I thought maybe the system is smart enough to /i\.imgur\.com/i\.stack\.imgur\.com/g on it's own to correct older images on edit, but if that's what is happening, then why does the edit history show me that Robert corrected it himself?

I am confused, explanations?
