Q: I have a MacBook Air as well as a Mac desktop–bought both of then the first week in May–If I have Picasa downloaded on both, can I group and organize the photos on one computer and expect the other computer to update those changes or do I have to organize and edit on BOTH computers ? If I do all the work on one computer, can I just copy all of the photos in their albums, with names, captions, etc., to the other computer ? How does this work to have all my photos organized the same on both computers? I know iPhoto will update through iCloud—so should I use iPhoto if keeping the same photos and organization is important to me for both computers !??
A: Picasa is not a multi-user program. This is probably its most requested feature. Each installation of Picasa includes a database which references all the pictures. This database will not be updated on computer B, when a change has been made to a photo on computer A. That said, Picasa can certainly be set to watch a folder that is synchronized by iCloud. I don’t have a Macintosh, but I have an iPad and I’ve set iCloud to keep “My Photo Stream” in sync between the iPad and my PC. It works great when I take a picture with the iPad, it shows up on my PC. But edits don’t seem to synchronize in either direction, even if I save them.
another option is a Dropbox folder. Keep all you pictures in a shared Dropbox folder, and set the location of your database to that same dropbox folder. This could work, but I haven’t done it. I would definitely do some experimenting before depending on this option.
Another possibility, if you have unlimited Internet connections, is to use Picasa Web Albums / Google+ photos as your intermediary. With two installations of picasa, if you log in to Google+ with the same account on both, then use Synchronized Web Albums – you should be seeing the same pictures on both. But … if your organization includes sub-folders, you’re out of luck with this option. Web Albums cannot have sub-albums. Not yet anyway.
