I just read that Google has released Picasa for Linux. Google has set up a main Picasa for Linux page and a download page. I installed the .deb from the download page on my Ubuntu Dapper laptop. I noticed that the only dependency in the .deb was on libc6 >=2.2. The download page states that WIne and the gecko engine are included in the download.
Here is a screenshot of Picasa running on my laptop:
It’s hard to see from this screenshot, but the menu items in particular suffer from the standard Wine look and feel. Otherwise, it looks really good. The little bit of functionality I played around with seemed to work OK. I haven’t had a chance to plug in a camera or to index thousands of images yet. I find this an interesting port to Linux. It’s not something I’m particularly excited about since my wife is the one who manages the photos. I’m glad to see the effort, nonetheless.
