Move2Picasa.com lets you connect to your Facebook account, after which all your Facebook photos and albums will automatically be migrated over to Google’s Picasa service.
It takes quite a time to move it, but those who want to transfer – its worth the wait, if you are about to shift loyality from FB to Google+ , this is the right option.
Drawback: You cannot transfer specific photos or albums right now. You need to transfer the entire thing or you get nothing.
