How to obtain iPhoto 11

Hi!

I own an old MacBook (late 2007). My OSX version is 10.7.5 (it's the latest release allowed on my Mac) and I use iPhoto 09 (8.1.2). It stopped working correctly (no maps are displayed on Places) and I would like to upgrade it. Obviously I can't install Photos, and I looked for iPhoto 11 but it seems impossible to purchase from app store or Apple's web site.

I found this page: https://support.apple.com/it_IT/downloads/iphoto, but only updates are available there.

Anyone knows how to obtain a copy of latest version of iPhoto for my Mac?
