But why is it being cranky about undoing it? In the post below the leading photograph's centre of interest was in the lower half, so kinja's especially helpful cropping makes it valueless. So I took it upon myself to crop the picture for and with the human eye. I edited the post to delete the former tall picture and replaced it with a short one.
Why then, at least so far, is the old tall and stupidly cropped picture still in the o-deck page view?
