FWIW, I initially looked at this thread on my iPod Touch, so basically a phone-less iPhone. The top narcissus thumbnail was easy to see, the lower one was too teeny to show clearly on the small device. So for anyone using a smartphone the existing thumbnails work better IMHO. I understand the concern because I once or twice posted a picture to illustrate something and the salient part of the image was off to one side and thus omitted from the thumbnail. Just something I figured I'd have to work around in future. Now with everyone using different devices from large desktop monitors to smartphones, it means we don't all have the same perspective.
