There are Picasa 2 installers available for Linux (.bin, .rpm, .deb). Apparently it uses Wine to run. I already have Wine installed on my laptop for other purposes, so instead of using them, I opted to install the Ms Windows version of Picasa2 on my Feisty. Beside the download size is far smaller than all of the Linux installer (since they are bundled with Wine).
If you haven’t installed Wine, you need to
sudo apt-get update
sudo apt-get install wine
Download the latest Windows version of picasa here, and double click the downloaded file to install Picasa. Picasa can be found on Applications>Wine>Programs>Picasa2.
There is downside to this method. It will recognize your folder trees just the way any application that runs under Wine. Means, It’ll recognize your home and desktop just fine, and slightly confuse you on other mounted partitions(driver letters instead of names) and root (“/”) folder. All function seems to be working as it should be. I am able to import and export photos from folders and external storage/devices, all image manipulation functions are working, and the upload function works fine too.
