Share the image on flickr

I am developing a app where i want to load the images开发者_Go百科 on flickr. I have seen the Snap and Run project where i tried to share the image using my API key but cannot do it. Can anyone help me with this as I am not able to do this.

I would recommend looking at the Stanford course for iOS development as there is a great sample app on using Flickr. Pay particular attention to the FlickrFetcher class http://www.stanford.edu/class/cs193p/cgi-bin/drupal/downloads-2011-fall lecture 9 :)
