thanks klondike. but yeah, when i said 10 galleries I meant for the london one. Even though I like pictures from the other rides, I'm only searching heavily for london right now haha.
Have you tried using hivemind? It seems to be able to find new photos:

also, with flickr, there's an option to not have photos come up in search results, so there may be many others we don't know of yet.
