I'm Caroline and I live in South London. I'm not sure how much detail Wikitravel wants on London but I am happy to add to it.
I also have lots of photographs released under Creative Commons which I took for Wikipedia. You can find them linked from my wikipedia user page (they are released under the GFDL and CC-BY-SA). I realise the project tries not to be image heavy.
I will upload anything I think is useful.
If we need an image of anywhere in London I will go and take it ;) - let me know Caroline 11:38, 28 Jul 2004 (EDT)
