iPhoto DMG OS X 10.7.5

Recently I've formatted my Mac Book Pro and I backuped some archives and some Apps. After the formatting I was checking if everything was ok, then I remebered that I didn't checked the iPhoto Library that I've backuped. I tried to open but there wasn't no iPhoto installed, so I tried to download update of the iPhoto, but it asked to install the iPhoto before I can upgrade, then I tried to download iPhoto but it asks me to download the OS X 10.10 The Yosemite. I won't upgrade to Yosemite because it just makes the computer slower than it already is. I tried to find the iPhoto DMG 9.1 and the 9.2 but couldn't find ANYWHERE! So, what can I do to resolve this problem?

Thank you!
