I'm not so sure about the "as many examples as one would like" part. For example, I was following a thread in which someone made half a dozen posts in a row, all with the exact same gear, and each photo looked quite a bit like the others, same subject matter, parameters, etcetera. To me, it seemed a bit like spamming the thread. I didn't say anything because, as you've mentioned, some people believe the purpose of certain threads is to post images. I'm just saying that in my opinion which I kept to myself, one or two would've done the job. Also would've decreased the download time and data use...
