I'm trying to find pictures of the building that used to house my local library. We're celebrating the 25th anniversary of our move to a new facility, and the building still exists (not sure what it is used for now). I can find it in Google Streetview, but it would be nice if I could locate some higher resolution shots.
Flickr has quite a good map feature for photos that have geo-tagging info:
You could try Google search by image. It allows you to upload an image and Google will try to find similar images of it. You can find a detailed explanation with instructions here.
