@bastianilso I generally use http://h45h.com which is a quick and dirty hack by @mikael - it uses the age-old HTTP method PUT and returns a URL with the filename directly related to the sha256 hash of upload contents. Code available here: https://github.com/mikaelfrykholm/h45h.com

To try it out: $ curl -s -T file.jpg http://h45h.com/
(should of course be made to use #https if there's any interest in using it)

But I guess there's also an interest in requesting a certain max hosting duration rather than keeping it indefinitely? Not that I know if imgur prunes or not...
