I was able to upload easily when I was using unity or gnome shell environment.. But after switching to full xubuntu 12.10.. The options are missing and I can't add them...
Anyone know why?
Shotwell 0.13, as Yorba has developed it, does not require Ubuntu Online Accounts. Ubuntu modified Shotwell to use their UOA system, which is why you're seeing this problem. We did not realize that this change would make Shotwell not work on Xubuntu. I don't know if Ubuntu is aware of this either.
I can offer three solutions for you:
We like to track all bugs with Shotwell, and so this one is ticketed here: http://redmine.yorba.org/issues/6069
UPDATE: Ubuntu has acknowledged this is a problem on their end and are working to fix it: https://bugs.launchpad.net/shotwell/+bug/1078642
UPDATE #2: Ubuntu has committed a fix to this problem, I don't know when it will be released.
