I've revamped my account on Flickr so that the photos are now in collections as well as sets, making it easier to find individual photos.
I've also laboriously indexed all my photos on Flickr's lovely mapping feature, so that you can see where in the world the photos were taken! If you click on my Index Page, you will see that beneath each picture, you can click on the word "Map".
This link (a geotag) will take you to the location of that photo on my Flickr map. You can use this feature in Flickr to search for people's photos of places from all over the world!
