Alas this requires a fairly block-shaped building where we can see sufficient edges, but might be useful for identifying where some photos are taken from:

In case it may be of interest, www.bellingcat.com too has interesting articles about geolocation (and other means of obtaining informations through open-source data). There are examples here on MB too (sorry, I can't remember exactly where).
