Dave Crossland took these photos of the WTF conference held in Leytonstone, London, in 2004. I found references to them on the web in 2006, but the photos themselves had disappeared, so I asked Dave if he still had them. He did, and he sent me a tarball releasing them under the GNU FDL. So here they are! Thanks Dave!
