How to determine if a user is logged into flickr?

Question

What is the right way to find out if a user is signed in to Flickr? I have an iframe in my application that allows the user to upload their images from Flickr. But if the user is not registered with flickr then flickr redirects me from iframe to yahoo homepage.

I would like to do the following: - Check if the user is registered in flickr, if there is one, and then upload his images in the iframe. - Else, open a new browser window that will allow the user to enter their credentials to log in to flickr.

Any suggestions from experts?
