I'd been very fond of Google's Picasa web albums, but about a month ago the iPhoto '08 broke the Google (Picasa) Export Plug-in. It's been a month now and there's been no official admission from Google of the problem and no fixes.
It's time for OS X users to look somewhere besides Google. Too bad the .Mac photo sharing doesn't support full res upload/download. I'll be looking around, suggestions welcome!
Update 9/15/07: A Google Picasa developer commented on my blog, see comments. The good news is that he's actively working on an update that will announced on the Google Mac blog. I don't agree that a single, increasingly buried, comment on the help forum counts as sufficient notification of the problem -- Google should have updated their download page. I haven't come across any alternative I like as much as Picasa web albums, so with this additional notificaton I'll keep waiting.
