Picasa metadata storage bug
Taken aimlessly from a car in New York City last month just after driving by the World Trade Center site. It was serendipitous: I only noticed the airplane later when triaging photos. And no, I do not find this amusing.
I’ve been trying to use Picasa2 for organizing my fledgling photo collection. It is marvellous in concept and very usable in practice, except for a nasty bug.
Here’s the bug: I create and assign labels to a bunch of pictures, then exit Picasa, then open it again, and the new label assignments are gone.
When I close Picasa I can see .PAL files being created in C:\Documents and Settings\Gulli\Local Settings\Application Data\Google\Picasa2Albums\blahblah. Each .PAL file contains XML describing a label and referencing the photos having that label. Right until they are all deleted when I open Picasa again.
Here’s the workaround: point Picasa to my picture folder with “Scan Once” instead of “Watch for Changes.” Of course I lose the watch-for-changes feature. But my labels stick.
Here’s my guess: apparently when I start Picasa, “Watch for Changes” does not recognize my picture files as being the same ones it indexed previously … so it regards the previously-indexed files as “lost” (and thus throws away the label information associated with them) and indexes them again as if they were new. So labels are lost each time.
I don’t know why it would do that. I am running Windows XP for 64-bit systems, but I got this bug in my normal 32-bit XP installation too. I store my pictures on an internal drive, not a network share.
Is anyone else experiencing this?
So for now I won’t use “Watch for Changes.” Instead, I’ll import manually when I have new or changed pictures. And wait for Google to fix this in the next release. [In which I hope they will also add support for .CR2 files, the raw photo format from newer Canon EOS models. Won't they? Please?]

The same happened to me after over six months of using Picasa to archive and sort pictures. I used labels to tag pictures for exporting them on my website.
At first I thought that happened because my Win XP just came back from hibernate and I started Picasa before the DHCP request was finished. (My machine is configured to get its network settings from my server machine). Because most of the pictures are also on the server, which was just not yet accessible on startup of Picasa, this might have triggered a rescan for pictures, loosing the tags information.
But that’s just a guess. Afterall this happened for the first time.
Just wanted to share my experience,
