Changes I've made: Cutting off parts of the photos so they fit in the collage.
The bottom-right photo is from here: http://wikimapia.org/6175089/ro/Centrul-de-Afaceri#/photo/7456502 According to the photographer, it's copyright-free as long as the source is mentioned. Proof is here (the language is Romanian): http://wikimapia.org/#lang=de&lat=51.000000&lon=9.000000&z=12&m=w&show=/user/messages/?sid=1807658&rid=2677381&lastmessage
The one remaining photo is my own work.
Every photo I've used, that wasn't made by me, is copyright-free, according to the photographers (see links).
