Install wine, sane, cabextraxct.
Download picasa 3.6 (http://dl.google.com/picasa/picasa36-setup.exe)
From terminal run command below for configuring wine environment and in resulting dialog go to in the “audio” tab, let wine make its audio configuration, test the audio with the "test" button. When that's done, install picasa. I did not need to install or run winetricks.
env WINEPREFIX="/home/$USERNAME/.winepicasa" winecfg env WINEPREFIX="/home/$USERNAME/.winepicasa" wine picasa36-setup.exe
