Which Fotomagico should I get?

Hello, I run an iMac with OSX version 10.8.5 (2014),processor 3.4 Ghz i7, memory 16Gb 1600 Mhz DDR3
Startup disk is Macintosh HD.
My question is I tried to upgrade the OS to El Capitain a few years ago. But this caused problems with other functionality. So I quickly returned to the Snowleopard system 10.8.5
I have used this system ever since. My question is…“Is there a Fotomagico version I can install onto this system”? If there is, please can you point me in the right direction. I would love to load the latest version of Fotomagico but I am terrified that the OSX upgrade needed is going to knacker my system again.
Many thanks for any suggestions.
