A random selection of vertical(ish) photos:
113-124 (all of one single area)
628,632,633,636,637,638 (all of the centre near the bridges)

I agree a systematic approach to tagging all the photos would be
better (anyone want to code up a tagging script?) but in the mean time
these would be good ones to rectify.
