Found a dead link to a flickr image like http://farm3.static.flickr.com/2085/2177060015_258bcfaff9_m.jpg and want to find out which user posted it, more images by that user, see the full-size version, etc?
From the URL you’ve got take extract the image name (2177060015_258bcfaff9_m.jpg). The first part is the photoID, the second part is the hash/salt and (if there) the third part the size (Full format: photoId_hash_size.jpg).
Now append that photoId to http://flickr.com/photo.gne?id= The example above would be transformed to http://flickr.com/photo.gne?id=2177060015
