Got a link like //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? Seek no longer, the answer is very simple!
From the URL you’ve got take extract the image name (
2177060015_258bcfaff9_m.jpg) and split it on the underscore. The first part is the
photoID, the second part is the
salt and (if there) the third part the
size (Full format:
Now append that
photoId to http://flickr.com/photo.gne?id= and *MAGIC* there you have it, the Original Flickr Photo URL (and the user) The example above would be transformed to http://flickr.com/photo.gne?id=2177060015
UPDATE 2008.01.18 – In related matter these might be of interest too: Flickr Hack – All sizes for all pics & My most interesting (best viewed) Flickr pics (replace that ID with your own Flickr ID to watch yours )
UPDATE 2010.11.07 – Bram.us visitor Robin Senior created a handy bookmarklet which does the job automagically. Drag this link to your bookmarks toolbar and click it whenever you have a static Flickr image URL open: Flickr Photo Page
UPDATE 2012.20.26 – Flickr itself has a detailed page explaining the Flickr full photo url format.
