Identifying Flickr Photos
This is a great little way of identifying Flickr photos. It is basically a reverse lookup of the user and photo data, given a link to just the image.
For example, given: http://static.flickr.com/72/184582779_5ba5cf7adf.jpg
1. Extract the photo ID. That's the part of the filename before the underscore. In this case, 184582779. 2. Plug the photo ID into the flickr.photos.getinfo call of the Flickr API Explorer at http://www.flickr.com/services/api/explore/?method=flickr.photos.getInfo 3. View the results, including the user who owns the picture and the page the picture resides on.
Note: that this does not work for pictures marked as friends-only, family-only, or private (unless you log in with the correct credentials.) It only works on public photos (which is 99% of Flickr anyway.)
