What steps will reproduce the problem? 1. Request info on some link, ie. http://api.bit.ly/info?version=2.0.1&hash=bnb3z&login=birdbook&apiKey=R_affa2d1307feebb21990cfff93220603&keys=thumbnail 2. See the result which includes thumbnail URLs, like: http://s.bit.ly/bitly/a9ZjH/thumbnail_large.png 3. See the output: XML which says: AccessDenied

I cannot find any documentation about using thumbnails of links. Nor can I find how to authenticate myself for using that URL. Where do I start looking? Googling about this sort of stuff leads me to nothing...

Same problem here ... today ... almost 3 months later. Get acccesdenied error when trying to display the thumbnail in any of the sizes. Any suggestions? Thanks.

the thumbnails are being depreciated; the thumbnail urls will be removed in a future api version
