Update: An acknowledgment of a mistake/bug was made in a post on a Google forum and indicated they are implementing a change. The change appears to have now gone through, and the previous existing functionality should now work. So, even Google makes big mistakes, which is ok, but I question why any changes at all would be made to existing API functionality. API changes should be branched out and push changes only to the new branch. That said, thanks to Google for the fix, though it took over 24 hours to get it in place, while many Picasa customers were left with broken galleries. I hope at some point Google will develop better support channels so developers are not left in the dark. I'm leaving the post up in case anyone needs to resolve this problem in the future if it happens again.
