A while back, I asked this question: How long is the Long Bridge of Volantis?
Since the question is very short and clear, and in what I perceive to be a somewhat fun/jovial spirit of scifi.SE, I added an illustrating image of a not-really long bridge.
Now, obviously there's no need for the image of that bridge. But I like the question better that way, and it got two upvotes and many interesting answers (not just mine...)
Earlier today, someone (with much more reputation than me) edited the question and removed the image of the bridge and the comment below. I rolled back the edit, but - was it legitimate/reasonable for me to do so?
