Hi Lee, I'm going to follow your suggestion and try to develop an application that synchronizes my photo web database with the photos that users upload on Picasa. I have many doubts about this implementation, maybe you can help me: - I have already been successful in that the users can login in my web with Authsub method authentification but I don't know how to get a user unique id. I got the user nickname, but this isn't unique. I want to get the email address. This would help me to save all the ids of the photos that the users have in Picasa in my database. When the user deletes a photo in Picasa, the nighty maintenance routine of my site will detect that there are differences and in the next user login in my web the user will be reminded that his photo no longer exists on my system. Also, with the unique id, the user could add some extra information about both his photos and his user profile. - When a user publishes a photo in Picasa do you know if I can get a public address to access it from my web?
As always, thank for you help and any advice. It's always apreciated!
