Phew, it took me 2 hrs of searching and some screwing up my system to get to install Picasa on Ubuntu 7.04
Hint provided by Google.
Q: Will Picasa run on a 64-bit version of Linux?
Yes, but you’ll need to configure the system to provide 32-bit compatibility libraries.
Please refer to your Linux distribution’s help information for more on how to establish those libraries. On Debian, they come in a package called ia32-libs.
Simple now.
Download and install ia32-libs. All that Google means by "establishing those libraries" is to get them installed.
sudo apt-get install ia32-libs
Then download the 32-bit version of Picasa .I was using Ubuntu, so the .deb extension.
By default,it is downloaded to the Desktop directory. Similar instructions otherwise.
cd Desktop
sudo dpkg --force-architecture -i picasa_2.2.2820-5_i386.deb
Changes will be needed to the package name as per the version downloaded.
Messages(*warning*) will be shown that the installation is 'forced'.

That was just for some fun, cmon guys ,it'll work unless you screwed your system beforehand :D
