Q: The title says all, and s/he who answers is awesome!
A: well you can simply type location or address in search box. if the location you are interested in is some small village or something like that, there won't be pictures, but everything else will work. you can also browse by tags http://www.flickr.com/photos/tags/ i.e. i typed damplein (it's main city square in amsterdam netherlands) in search box and in search box by tags and found plenty of photos.
